Why choose this 13×19" size?

When 12×16" starts to feel tight, 13×19" adds just enough capacity for hoodies, jeans bundles, thicker knitwear, and small to mid-size boxed products without jumping to heavy postage bands. The neutral grey finish hides contents and resists scuffs in transit, keeping parcels clean and professional.

Who it’s ideal for

• Apparel & fashion: hoodies, jogger sets, stacked tees, heavier knitwear.
• Shoes & accessories: compact shoe boxes, belts, caps, scarf sets.
• Home & textiles: cushion covers, towels, throws, bedding in sleeves.
• Print & kits: catalogues, A4+ packs, subscription kits, DIY bundles.
• Marketplace sellers: fast, tidy packing for mixed order profiles.

Fit & packing guidance

• Best fit: hoodies, jeans bundles, A4+ folders, compact shoe boxes, boxed gift sets.
• If it’s slimmer: step down to 12×16" to cut void space.
• If it’s bulkier: step up to 14×21" (or 15×18" for wider apparel stacks).
• Corner care: pad sharp inner-box edges to reduce punctures.
• Flatten air: press out air so labels sit flat and parcels stack neatly.

Key benefits

• Self-seal, tamper-evident closure for rapid packing and fewer tape rolls.
• 60-micron co-extruded film helps resist tears, splits and scuffs.
• Moisture-proof / water-resistant outer for wet weather routes.
• Opaque grey for privacy and a clean, uniform look.
• Lightweight versus boxes — save on postage and storage space.
• Recyclable LDPE — please remove the glue strip before recycling.

Specifications

Eco & Materials

Material: 100% recycled LDPE (resin code 4), co-extruded for strength and opacity. Recyclable in many UK schemes — please remove the adhesive strip first. These bags are not biodegradable or compostable.

Strength & Protection

60-micron co-extruded film is puncture- and tear-resistant and moisture-proof. The self-seal, tamper-evident all-season adhesive forms a permanent bond once pressed, keeping contents secure from dispatch to delivery.

Storage & Performance

Store bags at 13–21 °C and out of direct heat or sunlight. Let cold stock acclimatise to room temperature before use to maintain adhesive performance.

Lightweight = Lower Postage

Our recycled LDPE mailers are exceptionally lightweight, helping you keep parcels in lower weight bands versus boxes — a simple way to cut postal costs without losing protection.

Size comparison (pick the best fit for each order)

For a tidy fit across order profiles, keep 12×16" on hand for slimmer items and 14×21" (or 15×18") for bulkier picks.

Packing tips to save time and reduce damages

• Use a light inner sleeve for dusty or powder-prone items.
• Fold garments flat; avoid hard creases that create sharp corners.
• Apply labels on a smooth, clean area; press firmly for reliable scanning.
• Add invoices/returns in a clear document wallet on the outside.
