Barrier substrate for packaging containers with excellent gas barrier properties. The barrier substrate is made by coextruding a polyolefin-based stretched film with two resin layers containing polyolefin as the main component and an optional adhesive layer. A vapor deposition film is then applied to the outer surface. The barrier substrate can replace metal-coated substrates for better recyclability. The polyolefin-based barrier has good gas barrier properties and can be used in packaging containers without delamination or corrosion issues when filled with reactive contents.

Packaging container with easy-to-separate lid and tray for recycling. The container has a lined tray with a weakened bond between the liner film and the tray. The tray has a gripping tab that is offset from the brim tab. This allows the lid to be easily separated from the tray during opening, as the lid's gripping tab won't adhere to the tray tab. The weakened bond prevents the liner film from sticking to the tray during separation. The lid and liner film can then be easily separated for recycling.

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.

A two-way rollable packaging box that can be recycled without using adhesives for fixed connection. The box has a unique folding structure with six outer walls, first and second side walls, first and second inner walls, and central side walls. The outer walls, side walls, and inner walls fold to create a box shape. The central side walls have wing pieces that connect to the inner walls. The box folds into a triangular prism shape. The side walls have through holes. The inner walls fold inward to hold the contents. The box has fixing and coupling parts at the ends of the outer and inner walls to secure the box when rolled. The box can be rolled and unrolled without adhesives or tape for sealing. It can be easily recycled since it's made of a single material without adhesives or plastics.

A PET bottle separation and recovery device that sorts and processes used PET bottles to increase recycling efficiency. The device has a holder, transfer unit, crusher, ring separator, and measuring unit. It measures transparency, contamination, and lid presence of bottles. Bottles are crushed and separated based on measurements to optimize recycling. Transparent bottles are shredded in one area, opaque ones in another, and contaminated ones crushed. This allows recycling of transparent shards, shredded opaque sections, and crushed contaminated parts separately.

Recyclable packaging material for dense item packaging applications like pet food bags that can be processed on conventional packaging equipment. The material is a multi-layer structure with a reinforcing layer made of polyethylene textile sandwiched between other polyethylene layers like film and sealant. This allows recyclability since the layers are all polyethylene. The reinforcing layer provides strength and puncture resistance. The layers are adhered together with tie layers.

Sealant film for packaging applications that enables recycling of mixed resin materials. The film has a layer containing recycled material with two or more resin types, followed by a separate sealant layer. The recycled layer has small, localized regions with lower transmission compared to the surrounding. These regions have maximum area and aspect ratio limits to prevent clumping. This allows recycling mixed resins while maintaining sealant and mechanical properties.

Recyclable food packaging without using plastic that still exhibits desirable moisture barrier properties. The packaging uses a barrier-type paper with a metallized layer sandwiched between non-barrier paper layers. The metallized layer provides moisture and oxygen barrier properties. To avoid recycling issues, the metallized layer is camouflaged by using non-shiny aluminum oxide coatings, white coatings, or laminating structures that hide the metallic appearance. This prevents the metallized layer from being mistaken for foil and removed from paper recycling lines.

A bottle made from recyclable materials other than glass that is easily separable for recycling. The bottle has a rigid shell with a flexible pocket inside to hold the contents. The shell attaches to a fixed tip and has a neck. The shell is made of cardboard, like a cylindrical tube with cutouts forming the shoulder and neck. The flexible pocket is made of natural fiber material like braided or knitted fabric. This allows the shell, tip, and neck to be easily separated for recycling after emptying the bottle. The fabric pocket can be made from materials like cotton or jute. The cardboard shell can be recycled along with paper. The tip and neck can be recycled with plastic. The fabric pocket can be recycled separately with textiles. This enables the components of the bottle to be recycled in their respective streams rather than as a mixed material.
