摘要： In an embodiment, a process for producing a functional-substance thin film material for which a required heating temperature for finishing is 100-130° C. is characterized in that a PP film 2 is releasably laminated to a surface of a PET film 1 with a non-silicone adhesive layer 3 so that the strength of adhesion of the PP film 2 by the non-silicone adhesive layer 3 is regulated so as to prevent the PP film 2 from suffering thermal deformation when a functional substance superposed in a thin film form on the other surface of the PP film 2 is heated to 100-130° C. in order to finally convert the functional substance into a functional-substance thin film material 4.

摘要： The invention relates to a process for preparing a sequentially stretched biaxially oriented film, comprising the following steps: a) Melting a composition comprising at least 50 wt % with respect to the total amount of the composition of a copolyamide comprising: i. At least 75 wt % monomeric units derived from caprolactam, and further monomeric units derived from diamines X and/or diacids Y and/or aminoacids Z in a summed amount of between 0.2 to 25 wt %; or ii. At least 75 wt % monomeric units derived from hexamethylene diamine and adipic acid, and further monomeric units derived from diamines X and/or diacids Y and/or aminoacids Z in a summed amount of between 0.2 to 25 wt %; into a polymer melt; b) Casting the polymer melt through a planar die to form a film of at least one layer and subsequently quenching the film to a temperature of below Tg of the copolyamide, while the film is transported in a direction, referred to as machine direction; c) Stretching the film obtained after quenching in a direction parallel to the machine direction (MD-stretching) with a draw ratio DRMD at a temperature of at least Tg of the copolyamide; d) Stretching the film obtained after MD stretching in a direction transversal to the machine direction (TD-stretching) with a draw ratio DRTD at a temperature of at least Tg+10° C. of the copolyamide; e) Heat setting the film obtained after cooling and stretching, at a temperature of between Tm−70° C. and Tm of the copolyamide; in which Tg and Tm of the copolyamide are determined as described by ASTM D3418-03, with a heating and cooling rate of 10° C. per minute, in which DRMD/DRTD is at least 0.8 and DRMD×DRTD is at least 10.

摘要： The disclosure relates to a nanocomposite polymeric film including a thermoplastic polymer matrix such as polypropylene or other polyolefin, a coupling agent-modified organoclay reinforcement, and a polymeric compatibilizer bound to the coupling agent-modified organoclay, in particular as a thin film with controllable thicknesses. The disclosure further relates to masterbatch additives formed from the coupling agent-modified organoclay and the polymeric compatibilizer bound to the coupling agent-modified organoclay as well as related methods for making the nanocomposite polymeric film and/or processing recycled plastics. The inclusion of the coupling agent-modified organoclay reinforcement improves the mechanical properties of the nanocomposite polymeric film and the rheological properties of polymer melts including the nanocomposite polymeric film components. The coupling agent-modified organoclay leads to strain-hardening behavior for the polymer melts, which in turn can improve extensional viscosity values and melt processability for film blowing.
