Multilayer structures useful for packaging bone-in meat or other like products are provided. More specifically, multilayer structures are provided that have sufficient rigidity, strength, tear resistance and puncture resistance to contain bone-in meat or other like products. In addition, multilayer structures are provided for packaging bone-in meat and other like products that can easily seal to itself or to other structures to provide the packages for the products. Moreover, the multilayer structures of the present invention may be biaxially oriented and heat-shrinkable.

Disclosed is a method of fabricating a plastic substrate for display enabling to protect moisture and oxygen gas permeating from outside by carrying out laser annealing on a barrier layer locally. The present invention includes forming a barrier layer of a silicon compound material successively on a transparent substrate, carrying out thermal treatment on the barrier layer locally.

Oriented poly(chlorotrifluoroethylene) based films comprising up to 1 pourcent by weight of copolymerizable comonomers as well as oriented poly(chlorotrifluoroethylene) films formed essentially of a homopolymer comprising no copolymerizable comonomers are provided; all of the films are formed from low zero strength time film forming resin compositions which are highly amorphous in nature, and which are subjected to a process which includes the steps of: preheating the film above its glass transition temperature, stretching the film to provide a film having a stretched:unstretched ratio of between about 2:1 to about 5:1, followed by annealing the film. The films feature excellent resistance to vapor transmission, particularly water vapor, and feature good physical strength characteristics.

Disclosed herein are methods for making asymmetric laminate structures and methods for reducing bow in asymmetric laminate structures, the methods comprising differentially heating the laminate structures during lamination or differentially cooling the laminate structures after lamination. Also disclosed herein are methods for reducing bow in asymmetric laminate structures, the methods comprising subjecting at least one substrate in the laminate structure to asymmetric tempering or annealing prior to lamination. Further disclosed herein are laminate structures made according to such methods.

摘要:
Multilayer structures useful for packaging products, such as bone-in meat, cheese and other like products, are provided. More specifically, the multilayer structures are useful for bone-in meat packaging, cook-in packaging, shrink film packaging and other like packaging. The multilayer structures are coextruded and have sufficient durability, strength, tear resistance and puncture resistance, while also providing oxygen barrier protection. In addition, the multilayer barrier structures are biaxially oriented so as to be heat-shrinkable around products.
摘要:
Multilayered polyamide composite articles comprising at least three layers that comprise aliphatic and semi-aromatic polyamides and that is better able to retain its mechanical properties at high temperatures and over long times are disclosed. Layers comprising aliphatic polyamides may optionally contain oxidation stabilizers. The articles may be in the form of tubes incorporated into a heat exchanger. Processes for their preparation are also provided.
