Polythene Bags, Light, Heavy Duty, Gripseal & Gusseted
Pack Exact supplies a complete range of polythene bags for parts, textiles, components and retail. Choose fast bench dispensing, secure gripseal closures, write-on panels for identification, or gusseted formats for bulky items. Pair with packing tape, protective packaging and labels for a complete pack.
Light Duty Dispenser Packs
One-at-a-time tear-off bags for quick picking. Ideal for fast-moving small parts, kit components and lightweight textiles.
Heavy Duty Poly Bags
Tougher gauges to resist punctures and tears for denser or abrasive items—hardware, engineered parts, stacked products.
Gripseal Bags
Re-sealable closure for rework and returns. Keep smalls, spares and samples secure without tape or heat sealers.
Gripseal Bags with Write-On Panel
All the benefits of gripseal plus a writable panel for codes, dates and batch details—perfect for QC and kitting.
Gusseted LDPE Polythene Bags
Expandable side gussets add capacity for boxes, textiles and irregular items. Available in clear, blue and grey options.

Choosing gauge, clarity & colour
Pick thickness based on weight, edges and handling frequency. Clear LDPE offers visibility for SKU checks and retail presentation; blue/grey can aid sorting, privacy and light protection. For garments and premium clarity, consider polyprop garment bags. For outward shipping, combine inner poly bags with cardboard outers or mailing bags.
Bench efficiency & sealing options
Use dispenser packs at each station to speed picking and reduce “bag nesting”. For permanent seals choose hot-bar heat sealing; for quick closure use tape or switch to gripseal formats. Identify batches with write-on panels or add labels to flat areas.
Complete your pack
Protect delicate finishes with tissue paper or cardboard sheets. Stabilise cartons using void fill & bubble, then seal and label with packaging tape and address labels.
Polythene Bags – Frequently Asked Questions
Light duty suits lightweight parts and textiles; step up to heavy duty for dense, sharp or abrasive items. When in doubt, choose a higher gauge or add internal protection such as kraft paper.
Gripseal bags are reusable and re-closeable, ideal for samples, returns and kitting where contents need to be accessed frequently without tools or tape.
The panel allows permanent pen notes (batch, date, SKU) without extra labels—ideal for quality control and parts identification.
Side gussets expand capacity and shape, fitting boxy or irregular items more efficiently and reducing stretch stress on bag walls.
Polythene bags are best as an inner. For outward shipping choose mailing bags or a cardboard outer depending on fragility and carrier requirements.
