Material Verification for Package Integrity

Gas barrier laminate, packaging material, and vacuum insulation material that have excellent gas barrier properties even after folding. The laminate has a specific structure with layers: a polyolefin base layer, a first polyvinyl alcohol (PVA) layer, a vapor deposition layer, and a second PVA layer. The vapor deposition layer is between the two PVA layers. The indentation hardness of the second PVA layer is 0.5 GPa or less. This laminate design provides improved gas barrier performance compared to mono-material polyolefin laminates after folding, which is important for applications like foldable packaging and vacuum insulation.

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.

A polyethylene multilayer substrate with improved ink adhesion, heat resistance, and recyclability compared to conventional laminates. The substrate has a specific layer configuration and has been stretched. It consists of layers containing high/medium density polyethylene, medium density polyethylene, and linear low density polyethylene. This sequence balances ink adhesion, heat resistance, and manufacturability. Stretching the substrate further improves properties. The stretched multilayer substrate can be used as a base for laminates like packaging materials, with improved ink adhesion and heat resistance compared to conventional laminates made by laminating different resin films. The laminates can also have better recyclability since they are made of the same polyethylene material throughout.

Gas barrier film, packaging material, and package with improved barrier properties for containing food, pharmaceuticals, electronics, and other products. The gas barrier film has a specific peak ratio in the infrared absorption spectrum of the undercoat layer to improve oxygen and water vapor barrier properties. The peak ratio is obtained by adjusting the absorbance heights of specific wavenumbers in the undercoat layer infrared spectrum. This improves barrier properties without using expensive materials like polyester films. The film structure is a stretched propylene-based polymer film with an undercoat layer and inorganic layer.

Packaging material with low variance in barrier properties to extend shelf life of packaged products without using excessive coating materials. The packaging material has a base paper with a specific weight range, and coatings with cross-linked hydroxy polymer and wax. The base paper weight is 30-90 g/m2 to balance homogeneity and barrier effect. The first coating forms an oxygen barrier with cross-linked hydroxy polymer, and the second coating forms a water vapor barrier with polymer and wax. This combination reduces variance in barrier properties compared to high-weight base paper or excessive coatings.

Packaging material with low variance in barrier properties like water vapor permeability to extend shelf life of packaged products. The packaging has a low basis weight paper base, an oxygen barrier coating with cross-linked hydroxyl groups, and a water vapor barrier coating with polymer and wax. Calendering between coatings smoothes the surface for low variance. The average water vapor permeability is 2-100 g/(m2*24h) with a formula for variance. This allows lower average barrier while reducing variance to extend shelf life compared to high average barrier materials.

Paper-based packaging material with improved gas barrier and heat seal properties. The packaging material has a laminate structure with a paper substrate, gas barrier layer, and heat seal layer. The amount of heat seal layer is carefully adjusted to balance gas barrier and heat seal performance.

Laminated metal sheet for packaging applications with improved adhesion and barrier properties compared to conventional methods. The laminated metal sheet has a predominantly uniaxially oriented laminate layer with an adhesion layer containing a specific copolyester and a bulk layer of poly(ethylene terephthalate).
