This 30-piece pack contains honeycomb kraft paper mailers with a 165×225 mm outer size and a 40 mm sealing flap. An important distinction: HC mailers are NOT bubble mailers but have a honeycomb structure — between the paper layers a breathable, cellulose-based cushioning structure provides the protection, without any plastic content in the envelope. The pack is intended for webshop owners, craftspeople and small businesses for whom fully plastic-free packaging is a primary consideration, for mid-sized items.
What is included in the 30-piece pack
The pack contains 30 honeycomb kraft paper mailers, each in 165×225 mm outer size with a 40 mm sealing flap. The total gross weight is approximately 0.86 kg, around 26 g per unit. The 30-piece quantity provides several weeks of basic cover for a mid-volume, eco-conscious webshop dealing in mid-sized items, or a permanent base stock for an organic cosmetics or herbal brand.
Material and honeycomb structure
The envelope is made of 100% kraft paper and does NOT contain an HDPE-based bubble film. Protection is provided by a honeycomb paper texture (hexagonal cells) sandwiched between the two paper layers: this structure cushions the contents with small cellulose chambers, fulfilling the mechanical role of a bubble lining on a purely paper-based basis. This means the entire envelope can be sorted into paper recycling, breaks down in both industrial and home compost, and leaves no lasting microplastic burden in the environment.
Size and use cases
The 165×225 mm outer size is well suited to mid-sized shipments: a book or notebook close to A5, a smaller herbal pouch, an organic cosmetic product set, a handmade piece of jewellery in a box, an essential oil bottle (with cellulose inner padding), a smaller garment (scarf), or several smaller items together. The 40 mm flap leaves room for a clean seal.
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. Since the whole structure is paper, the recipient can put the opened mailer into a single recycling bin — there is no need to separate plastic and paper layers.
Storage and shelf life
Store the envelopes in a dry, cool place, away from direct sunlight, either flat or in light stacks. Honeycomb paper can soften with moisture and the cells may deform — so storing directly on the floor or in a damp room such as a cellar or bathroom is not recommended. The adhesive strip's protective tape typically retains full tack for 12 to 18 months from production.
