The invention relates to a biaxially orientated, single or multi-layered porous film made of propylene homopolymer and/or propylene blockcopolymer and ß- nucleation agent. Said film has a Gurley value of between 50 to
摘要:
The invention relates to a biaxially oriented single-layer microporous film that has a shut-off function and is made of propylene homopolymer, propylene block copolymer I, and ß-nucleation agent. The melting range of the propylene block copolymer I starts at a temperature ranging from 50 to 120°C.
摘要:
The invention relates to a multilayer biodegradable film produced from a base layer and at least one cover layer, which has a reduced seam strength and which can be used as a cover film for containers. Containers that are sealed with the film according to the invention can be opened more easily than those sealed with conventional films.
摘要:
The invention relates to a single- or multilayer biaxially oriented film, which contains 70-100 % by weight polymer consisting of at least one type of aliphatic hydroxycarboxylic acid, and which is used in the form of an inner liner of a cigarette package.
摘要:
The invention relates to a biaxially oriented transparent polypropylene film having a good UV barrier. The film contains, in at least one layer, nanoscalar titanium dioxide. The total content of nanoscalar titanium dioxide in the film ranges from 0.5 to 1.5 % by weight with regard to the total weight of the film.
摘要:
The invention relates to a biaxially oriented microporous film composed of at least two coextruded layers encompassing an external shut-off layer and another layer, both layers containing a mixture of propylene homopolymer, propylene block copolymer, and ß-nucleation agent. The propylene block copolymer I of the other layer has a melting point exceeding 140°C, and the propylene block copolymer II of the external shut-off layer has a melting range starting at a temperature ranging from 50 to 120°C. The melting point of propylene block copolymer I is higher than the melting point of propylene block copolymer II.
摘要:
The present invention relates to a method for the sterilization of products by means of UV radiation. A product is first enclosed by a UV permeable packaging material made of polyhydroxycarboxylic acid, and subsequently sterilized in the packaged state by means of irradiation using UV radiation.
摘要:
The invention relates to a simultaneously drawn opaque biaxially oriented film made of at least one layer comprising COC. This layer comprises a cycloolefin copolymer (COC) at a concentration of 0.5 to 30% by weight, in relation to this layer, and a polymer made of aliphatic hydroxycarboxylic acid units. The method is particularly advantageous both for the production of PHC films having very low shrink values, and for the production of highly shrinking films.
