Abstract

The invention discloses a tensile-resistant and anti-breakage film material. The film material is prepared from raw materials in parts by weight as follows: 50-100 parts of polyethylene, 3-8 parts ofdiethylenetriamine, 5-11 parts of methyl oleate, 4-9 parts of methyl benzoylformate, 7-15 parts of dimethylolurea, 4-8 parts of tetrabutyl orthosilicate, 11-20 parts of octanedioic acid and 3-7 partsof methyl dihydrojasmonate. The tensile-resistant and anti-breakage film material has greatly improved tensile strength and elongation at break, has excellent tensile strength at the low temperature,has the wide use range and can be better applied to food and medicine fields.

Description

technical field [0001] The invention relates to a film material, in particular to a stretch-resistant and fracture-resistant film material and a preparation method thereof. Background technique [0002] Plastic film can be used in food packaging, electrical product packaging, daily necessities packaging, clothing packaging and so on. As plastic film is more and more widely used, people choose to use bags made of plastic film to hold items, and sometimes the items are too heavy to cause the bag to rupture, causing unnecessary waste. Therefore, the present invention provides a film material with good stretch resistance and fracture resistance and a preparation method thereof. Contents of the invention [0003] The object of the present invention is to provide a stretch-resistant and fracture-resistant film material and its preparation method, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present i...
