High-strength medical plastic bag and preparation process thereof

Abstract

The invention discloses a high-strength medical plastic bag and a preparation process thereof, and relates to plastic bag manufacturing. The high-strength medical plastic bag comprises the following raw materials in parts by weight: 50-65 parts of plant cellulose, 8-15 parts of linear low-density polyethylene, 1-5 parts of polymethyl phenolic aldehyde, 10-20 parts of plant starch, 15-20 parts of reed biochar, 4-12 parts of calcium carbonate whiskers, 1-2 parts of a silane coupling agent, 10-14 parts of a stabilizer, 5-10 parts of a plasticizer, 4-10 parts of nano montmorillonite, 3-6 parts of an impact modifier and 1-2 parts of a water repellent agent. According to the scheme, the photocatalyst bactericide is added into the main ingredients of the medical plastic bag and has an excellent photochemical effect, small organic molecules can be decomposed into carbon dioxide and water, on one hand, the self-cleaning effect can be achieved, on the other hand, redundant toxic and organic gas can be adsorbed, and harmful microorganisms such as fungi and the like can be killed, so that the diffusion concentration of the garbage contained in the bag to the surrounding air in unit time can be reduced, and the effects of inhibiting and killing bacteria are achieved.

Description

technical field [0001] The invention relates to the production of plastic bags, more specifically, to a high-strength medical plastic bag and its preparation process. Background technique [0002] Plastic bag is a bag made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. It is an indispensable item in people's daily life and is often used to hold other items. The advantages of extremely light weight, large capacity, and easy storage are widely used, but due to the shortcomings of extremely long degradation cycle and difficult disposal of plastic bags, the production and use of plastic bags are banned in some countries. Since June 1, 2008, China has implemented restrictions Plastic order: implement the system of paid use of plastic shopping bags in all supermarkets, shopping malls, bazaars and other commodity retail places. No plastic shopping bags are provided for free, and the production, sale and use of plastic sho...

[0002] Plastic bag is a bag made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. It is an indispensable item in people's daily life and is often used to hold other items. The advantages of extremely light weight, large capacity, and easy storage are widely used, but due to the shortcomings of extremely long degradation cycle and difficult disposal of plastic bags, the production and use of plastic bags are banned in some countries. Since June 1, 2008, China has implemented restrictions Plastic order: implement the system of paid use of plastic shopping bags in all supermarkets, shopping malls, bazaars and other commodity retail places. No plastic shopping bags are provided for free, and the production, sale and use of plastic shopping bags with a thickness of less than 0.025 mm are prohibited nationwide. bag

[0003] There are still some deficiencies in the use of traditional Chinese medical plastic bags in the prior art. Because areas such as medical operating rooms, inpatient departments, and hospital corridors all need to place a large amount of garbage storage equipment, and in order to improve the garbage storage equipment The utilization rate of garbage is usually put on plastic bags on the garbage storage equipment, and these plastic bags have relatively simple functions, because the garbage put in medical plastic bags carries a lot of bacteria and viruses, and it is easy to produce peculiar smell, if there is The appearance of mosquitoes is also easy to cause cross-infection. Therefore, there is an urgent need for a high-strength medical plastic bag and its preparation process in the market at this stage to solve the above problems
