120 Gauge Black Refuse Sacks

Our 120-gauge black refuse sacks provide a practical and economical solution for collecting everyday light to medium-duty waste. Their flexible polythene construction makes them suitable for offices, shops, schools, hospitality businesses, cleaning contractors and other commercial environments.

The opaque black material helps conceal the contents and, therefore, provides a neater appearance than transparent waste bags. Furthermore, the sacks help contain loose rubbish, dry waste and lightweight packaging while bins are in use.

Each sack features a gusseted construction that expands when filled. Consequently, the bag can accommodate more waste than a completely flat sack of a similar face width.

The open top also allows users to fit the sack over a compatible bin or waste container quickly. Once full, staff can gather and secure the top using a suitable tie or knot, provided sufficient material remains above the waste.

Each box contains 200 sacks, making this format particularly convenient for workplaces that require a regular supply of refuse bags.

120 Gauge Black Refuse Sack Size and Specification

The product specification is:

• Size: 18 × 29 × 39 inches
• Approximate metric size: 457 × 737 × 991mm
• Measurement order: face width × open width × length
• Thickness: 120 gauge
• Approximate thickness: 30 microns
• Colour: black
• Material: polythene
• Duty: medium duty
• Box quantity: 200 refuse sacks

We show the sack dimensions as face width × open width × length.

The imperial measurements form the primary product specification. Meanwhile, the metric dimensions are approximate conversions. Therefore, please use the inch measurements when you require the closest match to the stated size.

Understanding the 457 x 737 x 991mm / 18 x 29 x 39-Inch Measurements

The 18-inch / approximately 457mm measurement represents the face width of the sack while it lies flat.

The 29-inch / approximately 737mm measurement represents the total open width, including the material contained within the side gusset. As a result, this measurement shows the approximate width available when the sack opens and expands.

The 39-inch / approximately 991mm measurement represents the overall length from the sealed bottom to the open top.

Because part of the sack’s width forms the gusset, the bag will not necessarily fit a rigid item measuring the complete stated open width. Additionally, the contents will use some of the available length as the sack expands around bulky waste.

Therefore, always allow extra clearance rather than selecting a sack that only just matches the dimensions of the bin or intended contents.

120 Gauge / 30-Micron Thickness

These refuse sacks use 120-gauge polythene, which is approximately 30 microns thick.

This specification provides a useful balance between flexibility, storage efficiency and everyday performance. Consequently, the sacks suit routine light to medium-duty waste in many commercial and domestic environments.

However, gauge describes the approximate material thickness rather than a guaranteed carrying capacity. The amount a sack can safely hold also depends on several other factors, including:

• The type of polythene
• Material formulation
• Seam construction
• Waste shape
• Distribution of weight
• Presence of sharp edges
• Temperature of the contents
• Handling method
• Distance carried

Therefore, do not rely on gauge alone when assessing suitability. A sack may have sufficient capacity for bulky waste while still being unsuitable for the weight or shape of that waste.

Gusseted Construction

The side gusset remains folded inside the sack while it is stored flat. However, when the bag opens, this material expands to provide additional internal capacity.

Consequently, the sack can adapt around soft, bulky and irregularly shaped refuse more effectively than a completely flat bag. This construction is especially useful for paper towels, packaging film, wrappers and other lightweight waste.

Before fitting the sack, open the gusset carefully and check that the material has separated correctly. Otherwise, an unopened fold may prevent the sack from sitting properly inside the bin.

Although the gusset adds capacity, it does not reinforce the sack against sharp objects. Therefore, protect or separately contain pointed waste before disposal.

Suitable Light to Medium-Duty Waste

These 120-gauge sacks are intended primarily for light to medium-duty general refuse.

Suitable waste may include paper, tissues, disposable towels, wrappers, lightweight packaging, empty containers and general non-hazardous workplace rubbish.

In addition, the sacks can accommodate soft and bulky items that occupy volume without creating excessive weight. Nevertheless, users should avoid compressing waste too firmly, as this can force sharp corners or rigid objects against the polythene.

The suitability of a sack depends on the complete waste stream rather than the bin size alone. Therefore, inspect typical rubbish from your premises before ordering in quantity.

If your waste is consistently heavy, wet, dense, abrasive or sharp, select a stronger sack designed for that application.

Waste These Sacks Should Not Contain

Do not use these refuse sacks for:

• Broken glass
• Unprotected sharp metal
• Exposed blades or needles
• Rubble and building materials
• Bricks, tiles or concrete
• Heavy garden waste
• Hot ashes or embers
• Hot cooking equipment
• Large quantities of liquid
• Solvents or corrosive chemicals
• Clinical or infectious waste
• Hazardous substances
• Batteries requiring separate disposal
• Electrical equipment
• Waste requiring a regulated disposal sack

Sharp, hot, hazardous or clinical materials require suitable specialist containers and disposal procedures. Furthermore, never place liquids or leaking containers into the sack, as the top does not provide a watertight seal.

How to Choose the Correct Refuse Sack Size

Measure the external width, depth and height of the bin before selecting a refuse sack.

For a round bin, measure across its widest point and consider the complete circumference of the opening. For a rectangular bin, measure both the width and depth so that the sack can extend around all sides.

Additionally, allow sufficient material to fold over the rim. This extra material helps hold the sack in position and makes removal easier.

The sack should also be long enough to reach the bottom of the bin without stretching. However, excessive material at the base can become trapped beneath the waste and may make removal more difficult.

Because the contents use part of the available width and length as the sack expands, a sack that appears large enough while flat may fit tightly once filled. Therefore, request a sample if your bin dimensions are close to the stated sack measurements.

How to Fit a 120 Gauge Black Refuse Sack

First, remove one sack and locate the open end. Next, separate the sides carefully without pulling sharply against the seams.

Open the gusset fully and lower the sack into the empty bin. Then, push the base gently towards the bottom without stretching or puncturing the material.

Fold the open edge over the bin rim while keeping the sack evenly positioned. If necessary, use a compatible sack-retaining band or bin system to hold it securely.

Before adding waste, make sure the bag is not caught on sharp edges, damaged bin fittings or rough surfaces. Additionally, avoid stretching the sack too tightly across the bin opening, as this may place unnecessary pressure on the material.

Filling the Sack Safely

Place lightweight waste into the sack gradually and distribute it as evenly as possible.

Avoid dropping rigid or heavy items directly into the bag, particularly from a height. The impact may damage the bottom seam even if the item itself does not have a sharp edge.

Furthermore, do not compress the contents using your hands or feet. Hidden sharp objects may cause injury, while excessive pressure can puncture or split the sack.

Stop filling before the waste reaches the top edge. This leaves sufficient material for gathering, closing and handling the sack.

If the contents become heavier than expected, remove some of the waste or use a stronger sack. Never drag an overloaded sack across the floor.

Closing and Removing the 120 Gauge Black Refuse Sacks

When the sack is ready for removal, gather the open top carefully. Then, close it using an appropriate sack tie, cable tie or knot where the available material allows.

These sacks do not include an integral drawstring or adhesive closure. Therefore, ties must be purchased separately if required.

Lift the sack carefully while supporting the base when necessary. Do not rely solely on the gathered top when the contents are bulky or moderately heavy.

Moreover, avoid dragging the sack across concrete, rough flooring or external surfaces, as abrasion may puncture the polythene.

Dispose of the sealed sack through the waste stream designated by your organisation or local waste contractor.

Black Finish for Discreet Waste Collection

The opaque black finish helps conceal the contents, providing a tidier appearance in customer-facing, workplace and communal environments.

As a result, these sacks are useful for bins in offices, shops, hotels, schools, cafés, restaurants and event venues.

However, black sacks may not suit recycling or segregated-waste systems that require transparent bags, coloured sacks or printed identification. Therefore, always follow the colour-coding and separation procedures used by your organisation or waste contractor.

Never use a black sack to conceal waste that requires specialist identification, controlled handling or separate disposal.

Commercial and Workplace Applications

The combination of a familiar refuse-sack format, medium-duty material and a box quantity of 200 makes these bags suitable for regular commercial use.

Cleaning contractors can distribute boxes across different sites, while facilities teams can store them in central supply areas. Similarly, hospitality, retail and educational premises can keep stock near waste-handling points for convenient replacement.

Because the sacks store flat, they require relatively little space before use. Nevertheless, store the box in a clean and dry location to protect the material from heat, sunlight and contamination.

For workplaces with several waste streams, clearly label bins and train staff to use the correct sacks. This helps prevent recyclable, hazardous or specialist waste from entering the general-refuse collection.

Boxes of 200 for Regular Use

We supply these 120-gauge black refuse sacks in boxes of 200 bags.

This quantity provides a practical stock level for businesses, cleaning teams, hospitality venues and other organisations that replace refuse sacks regularly.

Additionally, boxed storage helps keep unused sacks together and protects them from dust and everyday handling. Store opened boxes in a designated stock area and rotate supplies so that older stock is used first.

The sales unit is one complete box containing 200 refuse sacks. Therefore, check the required quantity carefully when placing your order.

Food Contact Information of 120 Gauge Black Refuse Sacks

These refuse sacks are intended for waste collection. Do not use them to store, wrap or transport unpackaged food.

Furthermore, do not use them as food-preparation surfaces or for any application involving direct food contact unless separate documentation explicitly confirms suitability.

Food businesses may use the sacks for appropriate back-of-house waste, provided they follow their hygiene, waste-separation and pest-control procedures.

If you require confirmation for a particular application or need a Food Safety Certificate, 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, polythene construction 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, recycled content, 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 for their application before making a PPWR compliance claim.

Material and Responsible Disposal of 120 Gauge Black Refuse Sacks

These sacks use flexible polythene construction. However, refuse sacks containing general waste are normally disposed of together with their contents through the appropriate waste stream rather than recycled.

Clean and unused polythene film may suit specialist flexible-plastic recycling services, depending on the facilities available in your area. Nevertheless, many household kerbside collections do not accept plastic bags or flexible films.

Contamination with food, liquid, chemicals or general refuse can prevent recycling. Therefore, always follow the guidance provided by your local authority, facilities manager or commercial waste contractor.

Recycled material content may vary according to the product specification and stock batch. Please contact our sales team if you require confirmation of the recycled content of this product.

Important Safety Information

Keep unused refuse sacks away from babies and young children because the material can present a suffocation risk. Never use the sacks as toys, protective clothing or bedding.

Store unused sacks in a clean, dry place away from direct heat, naked flames and prolonged sunlight. Polythene can melt or burn when exposed to high temperatures.

Additionally, never place hot ashes, embers or heated objects into the sacks.

Do not overload the bags or fill them with waste that exceeds the strength of the material or seams. Similarly, protect the polythene from sharp corners, broken objects and abrasive surfaces.

Before lifting, check the sack for punctures, stretching or damage. If the contents are bulky or heavy, support the base or transfer the waste into a more suitable container.

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