This 35-piece pack contains pink HDPE bubble mailers with a 130×180 mm outer size and a 40 mm sealing flap. The outer layer is pink HDPE plastic that gives a fashion-forward look, especially suited to cosmetics and gift shipments, and provides water-resistant protection. The inner layer is an HDPE-based bubble film that uses small air pockets to absorb impacts during transit. The pack is intended for webshop owners, craftspeople and small businesses who want their packaging to be part of their brand's visual message.
What is included in the 35-piece pack
The pack contains 35 pink HDPE bubble mailers, each in 130×180 mm outer size with a 40 mm sealing flap. The total gross weight is approximately 0.46 kg, so the pack fits comfortably into a drawer. The net weight per unit is around 12 g — providing a particularly favourable postal cost for smaller shipments. The 35-piece quantity gives several weeks of basic cover for a mid-volume cosmetics webshop or a permanent home stock for a craft brand.
Material and bubble lining
The outer layer of the envelope is pink HDPE plastic — a robust, fundamentally water-resistant polymer that does not let through drizzle or warehouse humidity. The warm pastel pink tone harmonises particularly well with cosmetic, women-focused or gift-oriented brands. The inside is an HDPE-based bubble film that forms a cushioning layer of small air pockets around the contents and absorbs impacts.
Size and use cases
The 130×180 mm outer size is well suited to smaller items: a cosmetic sample, a smaller cream, serum or perfume, a handmade piece of jewellery in a box, an essential oil bottle (with cotton padding), a small apology-gift, or a pack of cards and stickers. The 40 mm flap leaves room for the seal, so you do not need to fill the envelope right to the edge.
Closure and opening
The inside of the flap carries a self-adhesive strip that can be sealed in a single motion once the protective tape is removed. The envelope gets a secure, tamper-evident closure: the recipient can only access the contents by tearing the flap, so any reopening is visible. The pink plastic layer is opaque, so the contents are not visible from outside.
Storage and shelf life
Store the envelopes in a dry, cool place, away from direct sunlight. The UV resistance of HDPE plastic is good, but prolonged sun exposure may fade the pink pigment — so it is worth keeping the stock in a closed drawer or cabinet. The adhesive strip's protective tape typically retains full tack for 12 to 18 months from production.
