EVOH (Ethylene vinyl alcohol copolymer)

EVOH (ethylene vinyl alcohol copolymer) combines the processability of ethylene polymers with the barrier properties of vinyl alcohol polymers, and has high weather resistance, wear resistance, oil resistance, mechanical strength, and elasticity. EVOH not only exhibits excellent processing performance, but also has excellent barrier properties against gases, odors, fragrances, and solvents. Its thermal stability allows multi-layer containers containing EVOH barrier layers to be reused, widely used in food packaging, oxide materials, and packaging of new energy battery raw materials. EVOH resin has the lowest gas permeability, although its hydrophilicity and moisture absorption may affect gas barrier performance, it can be effectively controlled through multi-layer technology. In addition, EVOH resin has strong oil and organic solvent resistance, as well as high mechanical strength, elasticity, surface hardness, and wear resistance, making it an ideal choice in various packaging applications.

Ethylene (ripening hormone)

Ethylene (ripening hormone) is a plant hormone widely present in plant tissues, which can promote fruit ripening, organ shedding, and aging. The discovery of ethylene dates back to the early 20th century and was not confirmed as a plant hormone until the 1960s. Ethylene is a compound that can release ethylene and is widely used in agricultural applications such as fruit ripening and cotton defoliation. Although ethylene is safe to use within the standard range, excessive use may lead to food safety issues. The use standards of ripening agents are not sound and difficult to regulate, so their safety is still controversial.

Vinyl alcohol

Ethylene alcohol is an organic compound with the chemical formula C2H4O. Ethylene alcohol and acetaldehyde undergo tautomerism and have a large equilibrium constant. Generally, the content of ethylene alcohol is very low. Due to the instability of vinyl alcohol, its polymer form, polyvinyl alcohol (PVA), is not prepared by monomer polymerization of vinyl alcohol, but by polymerization of vinyl acetate and hydrolysis of ester groups.

Patent: A new type of leak proof FIBC bags, ton bags

Patent number: 201920494758.3. This utility model discloses a new type of leak proof plastic container bag and ton bag, which includes a plastic bag body, an inner bag, a feeding port, an anti leakage belt, a nylon belt, a sling, a circular sewing fixing belt, a discharging port, an elastic belt, and a tight strap. The design of nylon straps and tight straps effectively prevents leakage of the plastic bag body, inner bag side walls, and discharge port, improving sealing and work efficiency. The top of the discharge port is equipped with a circular sewing fixing belt, ensuring a sealed connection between the discharge port and the inner bag, preventing items from leaking from the sewing area. This design is suitable for the transportation packaging of powdered, granular, and block shaped items in industries such as food, medicine, and chemical.
