White Woven Medium Sack 450mm x 600mm

Our White Woven Medium Sack provides a practical solution for storing, separating and transporting suitable agricultural, industrial, construction and commercial materials.

The woven construction uses interlaced polypropylene tapes to create a flexible sack that adapts around granular, bulky and irregularly shaped contents. Consequently, it is useful for materials that may place excessive strain on lightweight film bags.

Each sack measures 450mm x 600mm, equivalent to approximately 17.7 x 23.6 inches, and has an approximate 90-denier specification.

A single-fold sewn bottom closes the base, while the hemmed open mouth creates a finished edge for straightforward filling and handling. After filling, users can secure the opening with a compatible wire loop tie or another suitable fastening method.

The clean white appearance also provides a practical background for identification labels and handwritten product information, subject to testing the chosen label or marker on the woven surface.

These sacks are sold individually, allowing customers to order the precise quantity required.

White Woven Medium Sack Size and Specification

The product specification is:

• Nominal metric size: 450mm x 600mm
• Approximate imperial size: 17.7 x 23.6 inches
• Measurement order: width x height
• Material: woven polypropylene
• Colour: white
• Nominal specification: approximately 90 denier
• Construction: woven polypropylene tapes
• Base: single-fold sewn bottom
• Opening: hemmed open mouth
• Handles: none
• Integral closure: none
• Sales unit: sold individually
• Delivery: local delivery or collection only
• Product range SKU: WPS

The dimensions are nominal manufacturing measurements. Therefore, small production tolerances may apply.

The imperial dimensions are approximate conversions from the metric specification. Please use the millimetre measurements when you require the closest match.

Understanding the Measurements

The 450mm / approximately 17.7-inch measurement represents the width of the empty sack while it lies flat.

The 600mm / approximately 23.6-inch measurement represents the overall height from the sewn bottom to the hemmed open mouth.

These dimensions describe the flat sack rather than the internal measurements after filling.

As the sack expands around its contents, some of the available width and height creates depth. Consequently, a rigid object measuring close to 450mm x 600mm may not fit comfortably.

Always allow additional clearance around bulky or angular products. Furthermore, leave enough unused material at the mouth to gather and secure the sack after filling.

Understanding the Approximate 90-Denier Specification

Denier describes the linear density of the yarn or tape used within a woven material.

It should not be confused with:

• Polythene gauge
• Micron thickness
• Fabric weight in grams per square metre
• Internal capacity
• Maximum carrying weight
• Seam strength
• Puncture resistance

The approximate 90-denier specification forms only one part of the overall product construction.

The amount a sack can safely contain also depends on the weave, tape formulation, seam construction, condition of the material, weight distribution and handling method.

Therefore, do not use denier alone to determine suitability or calculate a safe carrying capacity. If a verified load rating or detailed technical specification is essential, contact our sales team before ordering.

Woven Polypropylene Construction

Woven polypropylene sacks differ from conventional polythene film bags.

Instead of using a single continuous sheet of film, manufacturers create the sack from polypropylene tapes woven together in intersecting directions.

This woven structure helps distribute pressure across the material and provides practical resistance to stretching and splitting during appropriate use.

The construction also allows the sack to flex around:

• Granular materials
• Irregularly shaped products
• Manufactured components
• Agricultural supplies
• Landscaping materials
• Hardware and fixings
• Bulky non-hazardous contents

However, woven polypropylene is not indestructible. Exposed sharp edges can cut individual tapes, while excessive weight can damage the sewn base or surrounding weave.

Inspect every sack before use and choose a specialist container where the contents present a significant puncture, chemical or handling risk.

White Colour and Product Identification

The white woven material creates a clean and practical appearance for agricultural, industrial and commercial applications.

Labels and identification marks may stand out more clearly against the white background than they would on a darker sack.

Businesses may use suitable labels to identify:

• Product type
• Batch information
• Storage location
• Handling instructions
• Customer details
• Waste streams
• Internal stock references

However, the textured woven surface may affect how adhesives, inks and markers perform. Test the chosen label or marker before applying it to several sacks.

The precise shade of white and the appearance of the weave may vary slightly between production batches.

Single-Fold Sewn Bottom

The bottom of the sack uses a single-fold sewn construction.

This manufacturing method folds the lower edge before securing it with stitching. Consequently, the sewn base provides a practical closure for suitable contents.

The bottom seam remains a critical load-bearing area. Therefore:

• Distribute the contents evenly
• Avoid dropping dense objects into the sack
• Do not allow sharp points to press against the seam
• Keep the stitching away from abrasive surfaces
• Inspect the seam before filling
• Support the base when handling dense contents
• Stop using the sack if the stitching becomes loose or damaged

A sewn base does not create a liquid-tight seal. Very fine powders may also migrate through the stitching or woven structure unless a suitable liner is used.

Hemmed Open Mouth

The sack includes a hemmed mouth at the open end.

The hem creates a finished edge that supports straightforward opening and filling. It can also help reduce fraying around the top during ordinary handling.

These sacks do not include an integral drawstring, adhesive strip or zip closure.

After filling, gather the open mouth and secure it with a compatible wire loop tie or another fastening method suitable for the contents and application.

Leave enough unused material at the top for effective closure. Overfilling may prevent the mouth from gathering correctly and can place unnecessary strain on the weave or seams.

Suitable for Aggregates and Landscaping Materials

The woven construction makes these sacks useful for manageable quantities of suitable aggregates and landscaping products.

Possible contents include:

• Sand
• Gravel
• Decorative stone
• Bark
• Wood chippings
• Dry soil
• Compost
• Small landscaping components
• Gardening supplies

Dense aggregates become heavy quickly. Therefore, do not fill the sack according to volume alone.

A partly filled bag of sand, gravel or soil may already reach the maximum weight that one person can handle safely.

Adjust the filling level according to the material’s density, the distance it must be moved and the handling equipment available.

Agricultural Uses

White woven polypropylene sacks are widely used for suitable agricultural and horticultural materials.

Potential applications include:

• Seed
• Fertiliser
• Animal feed where suitability is confirmed
• Garden products
• Planting materials
• Compost
• Dry agricultural supplies
• Harvested non-food materials
• Farm and stable supplies

However, the product name and polypropylene material alone do not confirm suitability for every agricultural substance.

Fertiliser, treated seed and other regulated products may require specific packaging, labelling, moisture protection or chemical resistance.

Similarly, animal feed may require packaging manufactured and documented for the relevant feed-contact application.

Always check the applicable regulations and request supporting documentation before using the sacks for regulated agricultural products.

White Woven Medium Sack for Solid Fuel and Kindling

These sacks may be suitable for certain dry solid fuels and related products, including:

• Kindling
• Dry wood pieces
• Manufactured fuel products
• Charcoal where appropriate
• Other cool, dry and compatible materials

Never place hot fuel, warm ashes, embers or recently burned material into the sacks.

Pointed pieces of wood may catch on the woven tapes or damage the seam. Therefore, arrange the contents carefully and avoid forcing oversized pieces through the opening.

Store filled sacks away from naked flames, ignition sources, excessive heat and prolonged sunlight.

Metal Components and Fabricated Products

The woven construction can accommodate suitable metal components, fabricated parts and workshop materials.

Possible examples include:

• Nuts and bolts
• Washers
• Brackets
• Fixings
• Small fabricated components
• Plastic and metal parts
• Manufacturing offcuts without exposed sharp edges
• Workshop supplies

Nevertheless, sharp metal can cut the woven tapes or damage the sewn base.

Protect projecting corners and separately contain blades, swarf, sharp offcuts or pointed objects.

A rigid inner container may be more appropriate where metal components could puncture the sack or create an injury risk during handling.

Suitable Industrial and Commercial Applications

These white woven polypropylene sacks may support storage, separation and handling tasks in:

• Farms
• Garden centres
• Landscaping businesses
• Builders’ merchants
• Workshops
• Factories
• Warehouses
• Distribution centres
• Hardware suppliers
• Construction companies
• Maintenance departments
• Manufacturing facilities
• Solid-fuel suppliers
• Agricultural merchants
• Property-clearance businesses

Their medium 450mm x 600mm format provides additional capacity while helping users maintain a manageable load.

Nevertheless, always test the sack with the intended contents before introducing it into a regular packing or handling process.

Materials These Sacks Should Not Contain

Do not use these woven polypropylene sacks for:

• Hot ashes or embers
• Heated components
• Free-flowing liquids
• Leaking containers
• Solvents
• Corrosive chemicals
• Clinical or infectious waste
• Asbestos or suspected asbestos
• Exposed needles or blades
• Unprotected broken glass
• Sharp metal swarf
• Flammable substances requiring approved packaging
• Batteries requiring separate disposal
• Pressurised containers
• Materials requiring UN-certified packaging
• Waste requiring a regulated or colour-coded container
• Unpackaged food without confirmed food-contact suitability

Hazardous, clinical, hot, sharp or chemically aggressive materials require suitable specialist containers and approved handling procedures.

Not Waterproof or Leakproof

The woven construction should not be treated as waterproof, airtight or leakproof unless a separate product specification explicitly confirms those characteristics.

Moisture, fine particles and powders may pass through:

• Gaps within the weave
• The sewn bottom
• The open mouth
• Areas damaged during handling

Do not use the sack for free-flowing liquids or leaking products.

Where moisture protection or fine-particle containment is required, use an appropriate inner liner or select a laminated or lined woven sack designed for that purpose.

Confirm that any liner is compatible with the contents and does not interfere with safe filling or closure.

How to Choose the Correct White Woven Medium Sack Size

Measure the complete width, depth and height of the intended contents before selecting a sack.

For granular materials, calculate the quantity required and consider the resulting weight as well as the volume.

For rigid products, measure the widest and tallest points. Then, allow additional clearance so that the item does not stretch or distort the weave.

Remember that the 450mm width is measured while the sack lies flat. Part of this measurement is used to create depth when the sack opens around the contents.

Allow enough material above the contents to gather and close the mouth.

If your application is close to the stated dimensions or involves heavy, sharp or valuable products, request a sample before ordering a larger quantity.

How to Fill and Close the White Woven Medium Sack

Place the empty sack on a clean, dry and stable surface.

Locate the hemmed open mouth and separate the sides carefully. Do not pull sharply against the hem or sewn base.

Where necessary, position the sack inside an appropriately sized holder to keep it open during filling.

Add the contents gradually and distribute the weight evenly across the bottom. Avoid dropping dense or rigid products directly onto the seam from a height, as impact can damage the stitching.

Keep all contents below the hemmed mouth and leave sufficient material for closure.

After filling, gather the opening carefully and secure it using a compatible wire loop tie where appropriate. A tying tool can help apply wire loop ties consistently.

Wire loop ties and tying tools are separate accessories unless the product listing explicitly states otherwise.

Alternative closures may be suitable depending on the application. However, confirm that the chosen fastening:

• Holds the mouth securely
• Does not cut the woven material
• Suits the shape and weight of the contents
• Meets any applicable transport requirements
• Does not create a sharp handling hazard

Do not rely on folding the open mouth alone where the contents could escape during movement.

Lifting and Moving a Filled White Woven Medium Sack

Assess the filled sack before attempting to move it.

The amount that can be handled safely depends on the contents, filling level, distance travelled and manual-handling procedures in place.

These medium sacks do not include carrying handles. Therefore, grip and support them carefully without pulling sharply against one part of the hem.

Support the base where the contents are dense or bulky. Additionally, use a trolley or suitable mechanical aid where the filled sack is too heavy or awkward for one person.

Avoid dragging filled sacks across:

• Concrete
• Gravel
• Rough flooring
• Sharp thresholds
• Building debris
• Tarmac
• Uneven external surfaces

Abrasion can damage the woven tapes, stitching and contents.

Reusing the White Woven Medium Sack

Woven polypropylene sacks may be reused when they remain clean, dry and undamaged.

Before reuse, inspect:

• The sewn bottom
• The stitching
• The hemmed mouth
• The woven tapes
• Areas exposed to abrasion
• Stretched or distorted sections
• Previous punctures
• Contamination from earlier contents

Do not reuse a sack that has contained hazardous, contaminated or unknown materials.

The performance of a previously used sack may differ from that of a new product. Consequently, use a new sack where reliable containment is particularly important.

Clean sacks only using a method compatible with polypropylene and the intended subsequent use. Make sure the sack dries fully before storage or reuse.

Food and Animal-Feed Contact Information

Do not use these sacks for direct contact with unpackaged food unless the current product specification and supporting documentation explicitly confirm food-contact suitability.

Polypropylene construction alone does not demonstrate compliance with food-contact requirements.

Similarly, do not use the sacks for animal feed unless the product documentation confirms suitability for the intended feed-contact application.

Food and feed businesses must consider hygiene, traceability, contamination, migration, pest-control and storage requirements.

If you require confirmation for a food, seed or animal-feed application or need supporting documentation, please email sales@expresspackaging.co.uk before ordering.

PPWR Compliance Information

Regulation (EU) 2025/40 on Packaging and Packaging Waste, commonly known as the PPWR, applies to packaging placed on the EU market.

We can provide available product specifications and supporting information to help customers complete their compliance assessments. However, polypropylene construction, potential reuse or potential recyclability alone does not confirm full PPWR compliance.

The responsible economic operator must assess the product and its intended use against all applicable requirements, including packaging minimisation, substances of concern, material composition, recycled content, reuse, recyclability, labelling and technical documentation.

Customers intending to place these products on the EU market should email sales@expresspackaging.co.uk to request the latest available documentation and confirm suitability before making a reuse, recyclability or PPWR compliance claim.

Material and Responsible Disposal

These sacks use woven polypropylene construction.

Clean and uncontaminated woven polypropylene may suit a specialist plastic-recycling service, depending on the facilities available in your area.

However, many household kerbside collections do not accept woven sacks or flexible polypropylene packaging.

Contamination with soil, feed, fertiliser, fuel, chemicals or industrial materials may prevent recycling. Therefore, always follow the guidance provided by your local authority, facilities manager or commercial waste contractor.

Where a sack remains clean and clean and undamaged, consider reusing it for another suitable application before disposal.

The current product information does not confirm a particular percentage of recycled content. Consequently, do not make a recycled-content claim unless supporting documentation provides the relevant information.

Important Safety Information

Store unused sacks in a clean, dry area away from direct heat, naked flames and prolonged sunlight.

Polypropylene can soften, melt or burn when exposed to high temperatures. Therefore, never place hot ashes, embers or heated products inside the sacks.

Do not overload the bags or fill them with contents that exceed the capability of the weave, sewn base or closure.

Protect the material from exposed blades, broken glass, sharp metal and abrasive surfaces.

Before lifting, inspect the woven tapes, hem and bottom stitching for damage. Support the base when carrying dense or bulky contents.

Always follow your organisation’s manual-handling, hygiene and product-handling procedures.

Keep unused sacks and any wire ties away from babies and young children. Never use the sacks as toys, clothing or bedding.
