Oil-stain-prevention packaging bag and preparation method thereof

Abstract

The invention discloses an oil-stain-prevention packaging bag and a preparation method thereof, and relates to the technical field of plastic products. The oil-stain-prevention packaging bag is prepared from the following components in parts by weight: 100-120 parts by weight of polytetrafluoroethylene, 20-40 parts by weight of polyethylene terephthalate, 2 to 4 parts by weight of glycerin, 10 to15 parts by weight of noctilucent powder, 10 to 20 parts by weight of microprisms, 2 to 4 parts by weight of stabilizer, 2 to 4 parts by weight of plasticizer, 10 to 20 parts by weight of calcium carbonate, 4 to 6 parts by weight of acrylic resin binder and 2 to 4 parts by weight of essence. The preparation method of the packaging bag comprises the steps of: main film production; reflective surface film production; mixing, namely, re-addition of a main film and a reflective surface film to a high-temperature rolling machine; addition of a filler layer; bonding of the surface film; cutting; andbag making. The packaging bag disclosed by the invention has obvious reflective effect, can remind pedestrians and vehicles to pay attention to avoidance, can provide light illumination in a dark environment, has a fresh smell, does not easily adsorb oil stains, and has high mechanical strength.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to an oil pollution-proof packaging bag and a preparation method thereof. Background technique [0002] Plastic bags are an indispensable item in people's daily life. They are often used to hold other items. They are widely used because of their cheapness, light weight, large capacity, and easy storage. Commonly used plastic bags for food are mostly polyethylene films. The film is non-toxic, so it can be used to hold food. There is also a film made of polyvinyl chloride, which is also non-toxic, but the additives added according to the use of the film are often harmful to the human body. It has certain toxicity, so this kind of film and the plastic bag made of this film are not suitable for holding food. Existing plastic bags only have a single layer of film and have the function of packaging. They cannot provide lighting in a dark environment, and cannot remind passing pe...
