STRUCTURAL ADHESIVE TAPE AND METHOD OF MANUFACTURING THE SAME
20220033686 · 2022-02-03 ·

Disclosed are a structural adhesive tape in which a mesh layer is located on one side or both sides of an adhesive layer, and a method of manufacturing the same. The mesh layer having a specific specification may be used and an adhesive layer including an epoxy resin with a solid phase and a liquid phase and a flame retardant plasticizer may be used introduced so that a tape sagging phenomenon can be solved while minimizing degradation in adhesive strength. In addition, the mesh layer may be used so that a usage temperature range may be extended from a range ranging from about 5° C. to about 35° C. to a range ranging from about 0° C. to about 40° C., and thus workability in high and low temperature ranges may be improved such that tape workability can be improved even in overseas factories with poor temperature conditions.

POLYESTER FILM INCORPORATING SILICONE FOR RELEASE OF CANNED MEAT PRODUCTS

Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The BOPET film has at least one outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. The BOPET film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. More particularly, the invention relates to a novel outer release layer resin composition comprising an ultra high molecular weight siloxane polymer and a polyethylene trephthalate resin; and an alkali-metal phosphate and a phosphoric acid compound added, during polymerization of the outer release layer resin composition, as a catalyst/additive package to the ingredients forming the outer release layer resin composition. A wax component is added in the outer release layer, for more robust release performance.
