What are the functions of a vest bag? What should be paid attention to when using it?
The main function of vacuum bags is to remove oxygen and prevent food spoilage. The principle is relatively simple: food spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) require oxygen to survive. In vacuum packaging, this principle is used to remove oxygen from the packaging bag and food cells, thereby depriving microorganisms of their survival environment.

What is a tank top bag? Where is it generally used?
Plastic bags come in many types, with one common type known as a "T-shirt bag." As the name suggests, this bag has a cute appearance, with handles on both sides resembling a T-shirt. T-shirt bags are arguably one of the most commonly used plastic bags. They are thicker than ordinary lightweight bags and have a relatively strong load-bearing capacity. They are commonly used to make shopping bags in supermarket, medium, and small sizes. T-shirt bags are not easily torn because of their thickness, and are typically not used once and discarded, but rather reused repeatedly to carry items.

Basic introduction to anti-rust film bags
“VCI anti-rust bags are not miracle bags,” many people have a misconception about anti-rust film bags. They think that anti-rust bags are functional bags used to solve metal corrosion problems. However, this is not the case. The VCI in VCI anti-rust bags only plays an anti-rust role, that is, it is only used to “completely” preserve stainless steel metal bags, so it will not accelerate rust. Yes, its function is similar to the skin care products we use. It can prevent metal surfaces from rusting and rusting, but it cannot solidify.

Which industries use VCI rust preventive paper?
As the name suggests, meteorological rust prevention is a volatile rust inhibitor, and VCI rust preventive paper is a high-tech rust prevention product made from dozens of chemical raw materials through chemical processes. VCI rust preventive paper is a volatile rust-proof packaging material made of volatile chemical corrosion inhibitor VCI molecules, which are uniformly coated on a neutral paper substrate and have good physical strength. At room temperature, the paper surface slowly releases gas. This gas can decompose with corrosive media such as moisture, carbon dioxide, sulfur dioxide, and hydrogen sulfide in the air to the metal surface, and form an invisible stable protective film, thereby protecting the metal and its...

In this industrial age, with the continuous development of science and technology, mechanical equipment, hardware products, and exported metal products all require VCI rust preventive paper. It has penetrated every part of our lives and is ubiquitous. It has excellent rust prevention properties. VCI rust preventive paper is frequently used in our lives, can prevent component damage, and its rust prevention effect can last for more than a year. It is used to protect parts with higher shelf-life requirements and prevent parts from being corroded. Compared with plastic film, this rust preventive paper contains a large amount of VCI volatile corrosion inhibitor chemicals, which is beneficial for long-term protection of parts from corrosion. At the same time, the anti-corrosion paper also has good
