A method for manufacturing a recyclable and moisture-proof packaging strip that is easy to recycle, has water repellency, low adhesion, and anti-static properties, and is environmentally friendly and moisture-proof. The method involves forming a double coating layer on the inner surface of the paper fabric constituting the packaging strip. The first coating layer is made with an acrylic resin composition. The second coating layer is made with modified calcium carbonate. This provides water repellency, low adhesion, and anti-static properties. The paper fabric with the double coating layer is overlapped and bonded to create a barrel-shaped packaging strip. This eliminates the need for synthetic resin films that can't be easily recycled.

Oxygen and moisture barrier packaging material that uses only polyethylene film to provide sufficient barrier properties. The material consists of layers like stretched polyethylene, blocking layer, adhesive layer, non-stretched polyethylene, and can have additional components like resin barrier layer, heat-resistant layer, and printed layer. The stretched polyethylene provides initial barrier, the blocking layer prevents contaminants from reaching the adhesive, and the adhesive bonds the layers. The non-stretched polyethylene seals the contents. The material allows recycling without reducing yield since all layers are polyethylene.

Two-component curing adhesive composition and laminate made using it that combines recyclability and biodegradability. The adhesive composition contains an oil/fat with an acid anhydride group and a curing agent containing an acid-modified polyol and an amine compound. The oil/fat provides the adhesive strength when cured. The modified polyol and amine compound catalyze the reaction between the acid anhydride group and hydroxyl groups to form a crosslinked network. This allows a recyclable and biodegradable adhesive for laminating films.

Packaging blends for clear PET bottles that can be recycled into clear PET without degrading quality. The blends contain a polyester like PET and a second polymer that forms a separate glass transition temperature. This prevents the second polymer from interfering with PET recycling. The blends can have high haze or opacity for opaque packaging. To recycle, the blends are treated to reduce opacity and transesterify the second polymer into the PET. This converts back to clear PET for recycling.

Packaging material made from recyclable materials like paper and pulp that provides good cushioning properties for shipping fragile items. The packaging material uses a specific binder containing polysaccharides and proteins, a softening agent like a urea derivative, and a foaming agent like sodium bicarbonate. This allows manufacturing foam packaging with low specific gravity and good cushioning ability. The foam material can be molded into embossed sheets or bonded to a base layer. The softening agent reduces migration of color from the foam to contact objects. The foaming process uses sodium bicarbonate to lower the foam density. The foam material can be used in composite products like cushioning layers, multilayer structures, and composite recycled materials.

Method for manufacturing sanitary product packages that enables recycling of the packaging materials and reduces environmental impact. The method involves collecting leftover resin film scraps from cutting and joining steps during sanitary product packaging. These scraps are then used to recycle the resin film for subsequent product packages. This allows making the recycled resin film color similar to virgin film by avoiding printing on the scraps. This enables printing the recycled film in desired colors for sanitary product packages. The scrap collection and recycling promotes using recycled materials and reduces waste compared to using all new resin film.
