Why this 17×22" size?

When 15×18" starts to strain, 17×22" adds the length and width you need for duvet covers, throws, knitwear bundles, large apparel stacks and boxed gifts—without jumping straight to heavy cartons. The neutral grey film hides contents, resists scuffs and looks clean on arrival.

Real use examples (what typically fits)

• Textiles & home: bedding sets, pillows, throws, towel bundles, large cushion covers.
• Apparel: winter coats, multi-item clothing bundles, chunky knitwear.
• Boxed goods: mid-size retail boxes, gift sets, components with inner wrap.
• Print & fulfilment: bulk A4+/tabloid packs with sleeves.

Fit & packing guidance

• Best fit: bedding/textiles, stacked apparel, larger boxed kits.
• If it’s tight at the seal: step up to 20×26".
• If it’s roomy: step down to 15×18" for a neater seal and lower postage.
• Corner care: pad sharp box edges; use a light inner sleeve for dusty or powder-prone items.
• Press out air: flatten before sealing so labels sit flat and sacks/totes stack cleanly.

Key benefits

• Fast self-seal, tamper-evident closure — no tape needed for most orders.
• 60 µm co-extruded film — resists tears, splits and punctures in courier handling.
• Moisture-proof / water-resistant for wet routes.
• Fully opaque grey — privacy and a professional look on arrival.
• Lightweight — helps keep parcels in cheaper bands vs cardboard boxes.
• Recyclable LDPE (code 4) — remove glue strip before recycling.

Eco & materials

Material: 100% recycled LDPE (code 4), co-extruded for strength and opacity. Recyclable at many UK supermarket soft-plastic return points. Not biodegradable or compostable.

Strength & protection

The 60 µm film gives dependable puncture and tear resistance on bulky packs. The permanent adhesive creates a tamper-evident bond once pressed, protecting contents through warehouse and courier networks.

Storage & performance

Store flat at 13–21 °C away from heat/sunlight. Let cold stock reach room temperature before use for consistent seal strength.

Lightweight = lower postage

Mailing bags reduce dead weight and parcel size compared with boxes, helping orders stay within Royal Mail Small Parcel and efficient courier tiers where appropriate.

Size comparison (choose the right bag for each order)

Buying guide: 15×18", 17×22" or 20×26"?

15×18" covers bulky apparel and small boxed gifts. Choose 17×22" for bedding sets, pillows and larger bundles (best all-round “XL” workhorse). Step up to 20×26" for heavy textiles or bigger retail boxes where the 17×22" seal feels stressed.
