Why this 17×22" size?
Compared with 15×18", 17×22" adds generous width and length for bulkier apparel and combined orders. It fits coats, padded jackets, chunky knitwear, hoodies plus jeans, and larger subscription or gift boxes without stressing seams. The bold purple film upgrades your brand look on Shopify, Etsy, TikTok Shop, Amazon and eBay—no custom print required.
Real use examples
- Padded jackets, thick hoodies, chunky cardigans and knit sets
- Multi-item apparel bundles (e.g., hoodie + jeans + tee)
- Larger gift sets or retail boxes (use corner pads for edges)
- Bulky merch, blankets, soft home textiles or warehouse returns
Fit & packing guidance
Best fit inside: up to approx. 410×540×90 mm. If the adhesive lip lands on a bulge or corners feel tight, step up to 19×24". For slimmer items, step down to 15×18". Add corner pads for boxed goods, and press out excess air before sealing to keep parcels neat and postage-friendly.

Eco & materials
Made from 60 µm, 100% recycled LDPE (code 4). Recycled film offers reliable strength with a lower material footprint than virgin plastic of the same gauge. These bags are not biodegradable or compostable; please recycle with carrier-bag return schemes where available.
Strength & protection
Engineered co-extruded film gives a tough, scuff-resistant outer and a secure inner layer for heavier packs. The permanent adhesive creates a tamper-evident seal that stays shut through sorting and transit. The deep purple film is fully opaque to protect buyer privacy and elevate the unboxing look.
Storage & performance
Store flat at 13–21 °C away from heat or direct sun. If stock arrives cold, allow to acclimatise to room temperature before use for best sealing performance.
Lightweight = lower postage
Mailing bags reduce dead weight and parcel size compared with boxes, helping you stay within cheaper bands with Royal Mail, Evri, DPD and other couriers. Use a slim inner box only when edge protection or presentation requires it.
