Advanced Filler Technologies for Package Enhancement

Packaging film with improved gas barrier properties and reduced polymer degradation when recycled. The film has a gas barrier layer, an adhesive layer, and a sealant layer. The gas barrier layer has a soft coating layer between the vapor deposition layer and adhesive. The coating layer's hardness is 1.15 GPa or less. The adhesive layer is made by bonding a polyolefin adhesive composition to the gas barrier layer via melt extrusion. The sealant layer contains polyolefin resin. This film design allows good gas barrier performance without decreasing the polyolefin content in the film. The coating layer softness relaxes deposition layer stresses to prevent cracking. The soft adhesive layer allows shrinkage without transmitting stresses. This preserves barrier integrity during processing. The soft coating and adhesive layers prevent polymer

Packaging wet pulp like cellulose in a way that reduces corrosion and mold growth while avoiding the need for large amounts of preservatives. The method involves treating the pulp slurry with a preservative, dewatering it to form a wet pulp lump, degassing the lump in a sealed bag, and sealing the bag to create a packaged wet pulp. The degassing step removes air from the bag to reduce pressure inside. This prevents oxygen-based corrosion and mold growth without using high preservative levels. The packaged wet pulp can then be stored without further drying.

Protecting and maintaining alignment of optical fibers in semiconductor packaging to prevent misalignment and signal degradation due to CPI issues like vibration, thermal cycling, moisture, and impact. The solution involves a resilient frame with a compliant solid base material that spans over the fibers to preload and secure them. The frame provides transverse pressure on the fibers to prevent misalignment during packaging and operation. The compliant base material prevents fiber relaxation and misalignment due to fiber softening at high temperatures.

Packaging material for roll-fed packaging machines that allows easy folding into packages without compromising sealing integrity. The packaging material has weakening elements on the fin edges. These elements are placed at transverse distances from the fin edges. When folding the material to form packages, the weakening elements guide the material bulging from the fin edges towards them. This prevents bulges forming inside the packages that can compromise sealing.

A PVDC (polyvinylidene chloride) emulsion for pharmaceutical packaging that provides improved barrier properties, thermal stability, and long-term stability compared to conventional PVDC emulsions. The emulsion is made by using a silica sol as the dispersant instead of traditional surfactants. This avoids issues like decomposition, hydrolysis, migrant formation, crystallization, and poor thermal stability when heating. The silica sol also improves the water vapor barrier performance of the coating. The PVDC emulsion formulation contains 35-50% vinylidene chloride monomer, 0.5-5% comonomer, 0.1-0.5% initiator, 0.01-0.1% stabilizer, 5-7% silane coupling agent modified silica sol, and 30-5

Packaging material and packaging made from a paper substrate with a water-soluble sealing layer applied to one side. The water-soluble sealing media, like PVOH, is only partially applied to one part of the sealing area before sealing. The other part of the sealing area contacts the applied sealing media during sealing. This allows reducing sealing media usage compared to fully coated seams. The water-soluble sealing media dissolves during packing or consumption, leaving behind a paper-only packaging.
