PHARMACEUTICAL PACKAGING SHEETS CONTAINING GRAPHENE
The present application relates to a pharmaceutical packaging sheets containing graphene and a method for manufacturing the pharmaceutical packaging sheet.
Flexible structure with perforation-free inflation channel
The present disclosure relates to inflatable flexible structures. An inflation region may run longitudinally through the inflatable flexible structure allowing the inflation of chambers. The inflatable chambers may be separable at transverse lines of weakness formed by perforations. The inflation conduit may be free of the perforation. Additionally or alternatively, the perforations may be chevron shaped.
POLYETHYLENE RECYCLABLE FILM WITH HIGH STRENGTH AND/OR BARRIER
Polyethylene recyclable composite article comprises multilayer film having first layer comprising polyolefin with a melting point 190 C., second layer comprising second polymer selected from amorphous polyamide, polyamide with melt point 191-205 C., polyvinylidene chloride w/melt point 191-205 C., and/or EVOH w/melt point 191-205 C., and tie layer between the first layer and the second layer. The multilayer film is bonded to itself or another component. The second polymer makes up 1 to 10 wt % of composite article weight, and composite article exhibits a composite melt index of from 0.5 to 4 grams/10 min at 190 C. and 2.16 kg in a Composite Melt Index Test. A corresponding polyethylene recyclable multilayer film also exhibits 0.5 to 4 grams/10 min at 190 C. and 2.16 kg in a Composite Melt Index Test.
IMPROVED PACKAGING CONSTRUCTIONS, MATERIALS, AND METHODS
The present disclosure relates to improved packaging materials and/or constructions, and methods of making and using them.
PACKAGING MATERIALS AND PACKAGING SYSTEMS
Packaging materials and packaging systems can include metallized polymer films such as metallized polyethylene films having a metallic layer and a polyethylene layer, where bubbles are attached directly to the polyethylene layer and the metallic layer opposite the bubbles is exposed to an environment surrounding the material or system. The packaging materials and packaging systems can be highly recyclable and highly insulating.
Method for producing packing sheet with improved insulation and storage properties
Provided is a method for producing a packing sheet with improved insulation and storage properties, which can greatly reduce logistics costs by minimizing a volume during storage and transportation and also greatly increase insulation.
Honeycomb sandwich sheet or panel, based on polypropylene, with a central thermoformed film
The present invention relates to a honeycomb sandwich sheet or panel, based on thermoplastic polypropylene, comprising a structure consisting of two flat outer films, at the top and bottom (10, 12), welded to an inner or central film (11) blister thermoformed (13), with blisters repeated in a regular and continuous pattern, wherein said inner or central film (11) is thermoformed on both sides or faces.
Method of fabricating bubble sheet for vehicles
A method of fabricating a bubble sheet for vehicles includes steps of: preheating a first polymer sheet; providing the first polymer sheet to a partially preheated pattern forming machine to form a pattern polymer sheet including a plurality of patterns having a prominent or depressed shape; and bonding the pattern polymer sheet and a non-woven fabric sheet.
Packaging laminate
A packaging laminate includes a core layer having at least one through-hole which on one side is covered by a barrier film and an outer layer of a polymeric material, wherein said outer polymeric layer and said barrier film are laminated to each other in a manner such that said polymeric layer and said barrier film are separated from each other along parallel, visually detectable air-filled channels formed by these two layers within the area of said at least one through-hole.
POLYETHYLENE LAMINATES FOR USE IN FLEXIBLE PACKAGING MATERIALS
Embodiments of a laminate structure for use in flexible packaging comprise a sealant film comprising ethylene-based polymer, and a multilayer polyethylene print film laminated to the sealant film. The print film comprises at least 3 layers and has an overall thickness from 15 to 30 m. The print film comprises a middle layer, an inner layer disposed between sealant film and the middle layer, and an outer layer, wherein the middle layer comprises at least 90% by weight high density polyethylene (HDPE) polymer having a density from 0.950 to 0.965 g/cc. The inner layer and the outer layer comprise linear low density polyethylene (LLDPE) having a density from 0.925 to 0.965 g/cc. The laminate structure yields desired optical and mechanical properties coupled with recyclability and improved printing efficiency, while maintaining these low thicknesses for the print film.
