摘要:
A carbon coated polymeric film is produced by Plasma Enhanced Chemical Vapor Deposition. An amorphous nylon layer having at least one exposed high energy surface is adhered to a polymeric substrate. Carbon is thereafter deposited on the exposed high energy surface by vapor deposition of a decomposable precursor in the presence of plasma.
摘要:
A multi-layer bio-based composite film with a bio-based heat seal layer. The compostable bio-based film can comprise a crystalline bio-based heat seal layer and an amorphous bio-based barrier web layer. The heat seal layer has a second heat melting temperature which is lower than its first heat melting temperature.
摘要:
Bio-based high barrier metalized film such as PLA or PHA has an adhesion layer coated or co-extruded with the bio-based film and a metal oxide is disposed on the adhesion layer. The adhesion layer can be a co-extruded polyethylene terephthalate, nylon, polyglycolic acid, or ethylene vinyl alcohol. The adhesion layer can have a coating of EVOH, a nylon/EVOH blend, PVOH, PVOH/EAA mixtures, or a primer.
摘要:
A process for manufacturing a metallized polymeric film to provide a structure possessing high metal-to-film adhesion and little, if any, tendency toward metal fracture is disclosed. In one embodiment of the process, at least one polyolefin layer is provided to a film which includes a substantially isotactic polymer having a degree of atacticity of no more than about 6%. The isotactic component is preferably polypropylene homopolymer. Other components include up to about 34% of an adhesive-promoting component which can be a C.sub.2 -C.sub.4 polymer, including homo-, co-, and terpolymers having C.sub.2 -C.sub.4 carbon chains, and a second isotactic polymer having a degree of atacticity of from about 6% to about 15%. The surface of the polyolefin layer is subjected to flame treatment followed by vacuum metallization of this surface (preferably with aluminum).
摘要:
A machine-direction oriented tape comprising a blend of 65-95% wt % HDPE and 5-35% wt % PP optionally including fillers and UV additives displays physical and UV stability properties at least equal to commercially available oriented tape produced from PP or PE and can be used to produce woven fabric for applications such as ground cover and FIBC bags.
摘要:
A multi-layer bio-based film with a paper-like, writable surface. In one aspect, the compostable bio-based film comprises a surface layer of a PHBV rich blend resin and an outer base layer of PLA or PHA.
摘要:
A skin layer of a thermoplastic polymer includes an additive to promote metal adhesion to the surface of this layer. This additive is one or more compounds of the formula, R-X, where R is an aliphatic hydrocarbyl group having an average of from 20 to 200 carbon atoms and X is a polar group, such as —COOH or —CH2OH. The film may be biaxially oriented and include a polypropylene core layer. The film may be metallized with an appropriate metal, such as aluminum. A heat sealable skin layer may be provided on the opposite side of the film from the metallizable skin layer.
摘要:
A laminated film structure that includes a primary web having a migratory additive in a first outer layer and a metallocene polyethylene in a second outer layer that can be laminated to a secondary web without treating the surface of the second outer layer with a primer or solvent. The primary web further includes a core substrate layer disposed between the two outer layers that can include a biaxially oriented polypropylene. The laminated film structures have improved bond strength between the primary web and the secondary web.
摘要:
A metallized oriented film combination having a propylene polymer substrate with a high density polyethylene skin layer on at least one side thereof and a thin metal layer deposited on the surface of the high density polyethylene.
