Strong 60 µm Eco Postal Bags – Pink 12×16"
The tough co-extruded film delivers excellent tear resistance and a permanent peel-and-seal closure. The vibrant pink colour adds personality and brand appeal while keeping contents private and protected.
Why this 12×16" size?
12×16" is a versatile mid-range size ideal for hoodies, jeans, small gift boxes or 2–3 folded T-shirts. It’s large enough for fashion and boutique orders but still light for cost-effective shipping. The pink finish makes parcels stand out on doorsteps and social feeds.
Real use examples
- Two T-shirts or one hoodie neatly folded
- Pair of jeans or light knitwear
- Gift sets, cosmetics kits or beauty boxes
- Small boxed accessories or handmade items
Fit & packing guidance
Fits contents up to approx. 285×380×60 mm. If the seal area is tight, step up to 15×18"; for slimmer orders, try 10×14". Always press out excess air for cheaper bands and cleaner presentation.
Key benefits
- Strong self-seal – tamper-evident and permanent
- 60 µm film for superior tear & puncture resistance
- Moisture-proof / water-resistant surface finish
- Opaque pink colour – stylish and privacy-safe

Eco & materials
Manufactured from co-extruded 60 µm recycled LDPE to cut virgin plastic use. Not biodegradable or compostable; please recycle through supermarket carrier-bag points.
Strength & protection
The film’s thickness guards against scuffs and splits in transit. A tamper-evident seal locks shut securely. The pink colour is fully opaque to protect buyer privacy and enhance brand presentation.
Storage & performance
Keep flat at 13–21 °C. Let cold stock reach room temperature before use to ensure a consistent seal.
Lightweight = lower postage
Compared with boxes, mailing bags save grams on every parcel. This 12×16" option hits a perfect balance between capacity and cost for most fashion orders.
