Embodiment Construction

[0029] The film of the present invention is made up of following composition: resin, filler and auxiliary agent, the proportioning of parts by weight of resin, filler and auxiliary agent is:

[0030] Resin:filler:auxiliary agent=100:50~200:0.1~5.

[0031] The resin is polyethylene or polypropylene or polyvinyl chloride or polyvinylidene chloride or polyvinyl alcohol or nylon.

[0032] The filler is calcium carbonate, or at least one of calcium carbonate and kaolin, mica powder, silicon dioxide and talcum powder.

[0033] Auxiliaries are coupling agents, stabilizers, plasticizers and lubricants, or coupling agents, stabilizers, plasticizers and lubricants and toughening agents, antioxidants, antistatic agents, ultraviolet absorbers at least one.

[0034] The cross-sectional structure of the composite paper-like film of the present invention is layered, and consists of an upper film 1, a lower film 3 and an adhesive layer 2 between the upper film 1 and the lower film 3. The a...

Abstract

The invention relates to a film for manufacturing a composite paper-imitated film, the composite paper-imitated film and a method for producing the same. The film comprises the following compositions by weight portion: 100 portions of resin, 50 to 200 portions of filler and 0.1 to 5 portions of additive which. The composite paper-imitated film is provided with an upper film and a lower film; an adhesive layer is arranged between the upper film and the lower film; and the orientation of a macromolecular chain inside the upper film and the orientation of a macromolecular chain inside the lower film are in vertical arrangement. The method for producing the paper-imitated film comprises the following steps: the mixing and stirring of raw materials; extrusion and pelletization; the manufacture and stretching of a billet; and compounding and film forming. The film has low cost and environmental protection; and the composite paper-imitated film has high strength and good using effect.

Description

technical field [0001] The invention relates to a film and a production method of the film, in particular to a film for manufacturing a composite paper-like film, a composite paper-like film and a production method thereof. Background technique [0002] The traditional production method of plastic biaxially stretched film mostly uses a single layer of ordinary plastic film to be heated, stretched longitudinally first and then stretched transversely, so that the polymer molecular chains are oriented separately in a high elastic state, and quickly This orientation structure is made by cooling below the glass state to freeze it. Due to the single-layer film biaxial stretching forming technology, the polymer molecular chains that make up the film can only be oriented in the longitudinal direction, and the other part is oriented in the transverse direction. Therefore, the tensile strength of the film does not reach the highest value, and the manufacturing cost is high. Contents...
