Poly Bags

Custom Poly Bags

Pack, organise and present your products with custom poly bags designed around their dimensions, weight and intended use. Any Custom Boxes supplies bespoke printed poly bags for UK retailers, e-commerce brands, clothing businesses, manufacturers, wholesalers and fulfilment companies.

From clear flat bags for product organisation to opaque mailing bags and resealable retail packaging, each bag can be customised in size, film specification, colour, closure and artwork. Your logo, instructions, product information or handling message can be printed directly onto the bag to create packaging connected to your brand.

The correct poly bag depends on what you are packing, how the bag will be sealed and the conditions it will experience during storage, display or delivery.

Custom Poly Bags Made to Your Size

Stock bags do not always provide the right fit. An oversized bag can create unnecessary loose material, while a bag that is too small may be difficult to close or place pressure on the contents.

Custom poly bags can be developed around the final product dimensions and required opening. Packaging may be produced for:

• Clothing and textiles
• Fashion accessories
• Printed documents
• Retail products
• Hardware and small components
• Spare parts
• Cosmetics in suitable primary containers
• Food products where an appropriate specification is confirmed
• Subscription products
• E-commerce orders
• Product samples
• Warehouse and fulfilment use

Provide the finished length, width, depth and weight of the product. Include any retail box, hanger, backing card, leaflet or accessory that will be placed inside.

Where the product is bulky or has an irregular shape, a gusseted bag may provide a more practical fit than a completely flat format.

Custom Printed Poly Bags With Your Logo

Custom printed poly bags allow your packaging to display your business identity while holding or protecting the product.

Your supplied artwork may include:

• Brand name and logo
• Product name or reference
• Size and colour information
• Usage or handling instructions
• Barcode or QR code
• Business contact details
• Website and social media information
• Recycling or disposal guidance
• Safety warnings
• Promotional messages

Printing may be applied to one or both sides, depending on the bag material and production specification. A simple one-colour logo can provide clear branding, while multiple colours may be considered for more detailed artwork.

Important text should remain readable against the selected clear, coloured or opaque film. Barcodes and QR codes need sufficient contrast and clear space around them.

Clear and Coloured Poly Bags

Clear poly bags allow the contained product to remain visible. They may suit clothing, components, printed materials and products that need to be identified quickly during storage or fulfilment.

Coloured and opaque bags can hide the contents and create a stronger branded appearance. They may be considered for mailing, retail orders, event products and promotional packaging.

Possible visual options include:

• Fully clear film
• Frosted or translucent film
• White film
• Black film
• Custom-coloured film
• Printed patterns
• Designated clear windows
• Coloured mailing bags

The final appearance depends on the film, ink and printing process. Pale inks may not remain visible on transparent material without an appropriate printed base.

Flat Poly Bags

Flat poly bags use a simple format with two sealed sides and an open or closable top. They may suit lightweight, flat or compact products.

Possible applications include:

• Clothing accessories
• Documents and printed materials
• Small retail goods
• Hardware components
• Product samples
• Craft materials
• Warehouse parts
• Promotional items

The top may remain open for manual sealing or include an adhesive strip, zipper or heat-sealable section.

A flat bag should include enough additional length for the closure. Product dimensions alone may not provide enough room to seal the bag correctly.

Gusseted Poly Bags

Gusseted poly bags include additional material at the sides or bottom that expands when the bag is filled.

They may suit boxed products, folded clothing, bulky items, multi-product packs and components requiring more internal volume.

Side gussets expand across the bag’s depth, while a bottom gusset can provide additional room near the base. The gusset dimensions should be selected according to the finished product rather than an estimated capacity.

Artwork should be prepared using the complete bag template because printed elements can disappear into the folds after filling.

Grip-Seal and Resealable Poly Bags

Grip-seal bags use an interlocking closure that allows the bag to be opened and closed repeatedly.

They may be useful for:

• Small parts and fasteners
• Jewellery components
• Samples
• Craft products
• Instruction sets
• Replacement pieces
• Accessories
• Products used in several stages

A write-on panel may also be added for product codes, quantities or handwritten notes.

A standard grip seal should not automatically be described as airtight, leakproof or child-resistant. Its performance depends on the closure, film, product and conditions of use.

Liquids, powders and regulated products may require a specialist tested closure or an additional primary container.

Self-Seal Poly Bags

Self-seal bags include an adhesive strip that allows the top flap to be folded and closed.

Permanent adhesive may suit single-opening packaging, while resealable adhesive can be considered where repeated access is required. The appropriate option depends on the product and customer experience.

Self-seal bags are commonly considered for clothing, documents, textiles, accessories and e-commerce fulfilment.

Adhesive performance can be affected by dust, moisture, storage conditions and repeated opening. Test the final bag with your normal packing process before placing a larger order.

Poly Mailing Bags

Custom poly mailing bags provide a lightweight outer layer for suitable e-commerce products. They may be used for clothing, soft goods, textiles, documents and products that do not require a rigid shipping carton.

Possible mailing-bag features include:

• Permanent adhesive closures
• Double adhesive strips
• Tear-open strips
• Return closures
• Opaque film
• Printed delivery messages
• Barcode areas
• Address-label zones

A mailing bag does not provide the same crushing or impact protection as a corrugated box. Fragile, sharp, heavy or liquid-containing products may require additional packaging.

The film thickness, seams and closing strip should be selected according to the product and proposed delivery process.

Garment and Clothing Poly Bags

Garment poly bags can organise folded clothing and help keep individual items separated during storage and fulfilment.

Bags may be developed for shirts, dresses, trousers, knitwear, sportswear and fashion accessories. Printed size information, product references and barcodes can make stock identification easier.

Possible features include:

• Resealable adhesive strips
• Ventilation holes
• Suffocation warnings
• Size printing
• Barcode panels
• Frosted film
• Branding and care messages

Ventilation holes can help trapped air escape when products are stacked or packed into a shipping box. Their number and position should reflect the product and bag structure.

Where a suffocation warning or another safety statement is required by your retailer, marketplace or destination market, provide the exact approved wording with your artwork.

Header and Hanging Poly Bags

Header bags can include a reinforced top section and hanging hole for use on suitable retail display hooks.

They may suit small accessories, craft products, hardware parts, stationery and replacement components.

The header can carry your logo, product name, barcode and other retail information. It may be printed as part of the bag or combined with a separate card, depending on the required construction.

The hanging section should account for the finished product weight. Heavy items may require a reinforced structure or alternative display format.

Poly Bags for Hardware and Industrial Products

Poly bags can organise screws, washers, fittings, cables, spare parts and other components.

The film specification should account for product weight and any sharp corners or projecting edges. Dense metal products may require a thicker film than lightweight textiles or documents.

Possible features include:

• Heat-sealed closures
• Grip seals
• Printed part numbers
• Quantity information
• Barcodes
• Write-on panels
• Hanging holes
• Multiple compartments

Sharp products should not be packed in a lightweight bag without assessing the risk of puncture. Protective caps, internal wrapping or a stronger outer container may also be required.

Food-Contact Poly Bags

Poly bags may be used for food only where the complete film, inks, additives and manufacturing specification are suitable for the intended food-contact application.

Tell us:

• What food will be packed
• Whether it is dry, oily, acidic or moist
• Whether the bag will touch the food directly
• The filling temperature
• Storage conditions
• Required shelf life
• Freezing or heating requirements
• Proposed sealing method

A general poly bag should not automatically be described as food-safe, freezer-safe, microwave-safe or suitable for hot filling.

The responsible food business should retain appropriate material documentation and approve all applicable ingredients, allergen, quantity, storage and business information before printing.

Polyethylene Materials and Film Thickness

Many poly bags are produced using polyethylene materials, including low-density and high-density variations. Different films can offer different levels of flexibility, clarity, stiffness and puncture performance.

The bag specification may be described using film type and thickness. A thicker film can provide additional material strength, but thickness alone does not determine whether a bag is suitable for a particular product.

Selection should consider:

• Product dimensions
• Finished weight
• Sharp edges
• Required transparency
• Closing method
• Packing equipment
• Storage conditions
• Delivery process
• Required printed appearance

Request testing or samples when the bag must meet a particular strength, seal or handling requirement.

Heat-Sealable Poly Bags

Heat-sealable bags can be closed using suitable sealing equipment after filling.

The required temperature, pressure and sealing time depend on the film and production setup. Incorrect settings can create weak seals, distortion or damage to the bag.

Businesses should test the chosen bag using their own product and sealing process. The seal area must remain free from dust, oil, powder and product contamination.

A heat seal may provide evidence that the bag has been opened, but it should not automatically be described as tamper-proof.

Printing and Artwork Options

Custom poly bags can carry simple or detailed printed designs.

Possible options may include:

• One-colour logo printing
• Multiple printed colours
• One-sided printing
• Two-sided printing
• Repeating patterns
• Product-information panels
• Barcode areas
• White ink beneath colour artwork
• Different artwork for product variations

The available print result depends on the film, bag style, ink system and order quantity.

Fine text should remain large enough to read, and important design elements should be kept away from seals, folds, zippers and adhesive strips.

Environmental and Recycling Claims

Poly bags should not automatically be described as recyclable, biodegradable, compostable, environmentally friendly or made from recycled plastic.

Recycling availability can depend on the polymer type, inks, adhesives, labels, contamination and local collection services. Flexible films may require collection through specialist or retailer-operated systems rather than ordinary household kerbside recycling.

Where recycled content, compostability or another environmental feature is required, request it as part of the formal material specification and retain supporting evidence.

UK businesses should also check whether Plastic Packaging Tax, Extended Producer Responsibility or carrier-bag charge requirements apply to their activities.

Wholesale Poly Bags for UK Businesses

Wholesale custom poly bags can help businesses maintain consistent packaging across product sizes, colours and fulfilment locations.

A shared artwork layout may use the same logo placement while changing bag dimensions, product references, warnings or barcodes for each variation.

Pricing depends on:

• Finished dimensions
• Material and film thickness
• Bag style
• Closure type
• Printing coverage
• Number of colours
• Gussets or ventilation holes
• Artwork variations
• Order quantity

Maintain a separate approved artwork file for every size and product variation to reduce printing errors.
