Water Vapor Permeable Shrinkable-Fabric

Номер: US20120015161A1
Автор: Gregory L. Todt, Seckin Ozol
Принадлежит: Transhield Technology AS

A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage.

Graft compositions, useful for tie-layer adhesives, are disclosed. The graft compositions comprise the reaction product of a live, grafted polyolefin and an olefin elastomer. The grafted polyolefin is first made by heating a polyolefin and an unsaturated monomer. Further reaction of the live, grafted polyolefin with an olefin elastomer provides the graft composition. Grafting efficiency is boosted dramatically by the presence of the olefin elastomer and use of the additional reaction step. The graft composition, when formulated into a tie-layer adhesive at low concentration, affords multilayer structures with good adhesion and high clarity.

A method of forming an article comprising the steps of The present invention relates to hot melt adhesives with wide service temperature ranges, making these adhesives particularly well suited for case and carton sealing applications that are exposed to extreme temperatures.Hot melt adhesives are applied to a substrate while in a molten state and cooled to harden the adhesive layer. The use of hot melt adhesives is widely used in packaging industry to seal containers, e.g. cardboard cases, trays and cartons. Many types of packaging applications require the use of an adhesive that is both heat resistant and cold tolerant. However, conventional hot melt adhesives exhibit strong bond strength at either the high or the low end temperatures, but not both. Polypropylene based systems have been utilized to improve heat resistance, but polypropylenes provide inadequate cold resistance because they become brittle at around 0° C. During transportation and storage, and depending on the season and location, the sealed containers are exposed to temperatures of from about −20° F. to about 140° F. Hence, there is a need for versatile hot melt adhesives with both good heat and cold resistances. The current invention addresses this need.The ...
