Hemostatic film formula hydrolyzed at high temperature

Abstract

The invention relates to a hemostatic film formula hydrolyzed at a high temperature. The formula comprises 60-100 parts of polyvinyl alcohol, 5-10 parts of polyethersulfone, 0.5-1 part of ethyl p-hydroxybenzoate, 2-8 parts of betaine polysulfonate, 0.1-0.3 part of ammonium carbonate and 15 parts of dibasic lead stearate 0.5nu. The formula is not hydrolyzed at the room temperature but hydrolyzed atthe temperature of more than 45 DEG C. Hydrolyzed products are harmless to the environment, the formula is simple, the production cost is low, and environment protection and safety are achieved.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a hemostatic film formula hydrolyzed at high temperature. Background technique [0002] Plastic woven bags are widely used packaging belts. Common products include feed woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags, fruit mesh bags, rice woven bags, flour woven bags, corn woven bags, etc. Its main production process is to use plastic raw materials to produce pellets, flat wire stretching, circular weaving cloth base, film coating, printing, cutting, sewing to obtain products, and finally package them for delivery. [0003] The hemostatic film hydrolyzed at high temperature is a water-soluble and degradable novel green packaging material, which can be widely used in the packaging of various products. It is environmentally friendly, easy to dissolve, safe and non-toxic. At present, there are many kinds of films on the market, but they are not easy to degrade, which ...
