Advantages of a square-bottom bag
Polymeric polymers (or synthetic resins) are the main component of square-bottom bags. To improve the properties of plastics, various auxiliary materials must be added to the polymer to meet people's various requirements for plastics, such as fillers, plasticizers, lubricants, stabilizers, colorants, etc., to become high-performance plastics. Square-bottom bags generally use synthetic resins as the main material, and are named for their square bottom. When unfolded, they look like a cardboard box, with variable length, width, and height, "tailor-made" according to the size of the product to be packaged.

What are the advantages of anti-rust bags? Which industries are they suitable for?
Rust preventive bags are a new generation of innovative, high-tech products in the field of metal corrosion prevention. After placing metal products requiring rust prevention into the rust preventive bag and sealing it, the VCI inside begins to sublimate and volatilize rust-preventing gas factors. These factors diffuse and permeate the surface of the rust-preventive object and adsorb onto it, forming a dense, monomolecular protective film. This isolates the rust-preventive object's surface from various factors that induce rust, thus effectively preventing rust.

VCI anti-rust bags have good plasticity, overcoming the shortcomings of insufficient protection of traditional anti-rust products; they have good transparency; the effective product protection time can reach 1-3 years.

How to test the airtightness of self-sealing bags?
Self-sealing bags can be used as inner and outer packaging for various small and medium-sized items (decorations, hardware, toys). They are made of food-grade stainless steel and can store various snacks, tea, seafood, etc. They are waterproof, odor-proof, moisture-proof, and insect-proof, preventing items from scattering; self-sealing bags can also be used to package clothing and other daily necessities. Anti-static self-sealing bags can be produced by adding anti-static regenerant during the film blowing process, generally used in the electronics industry.

What are the different types of self-sealing bags?
When we buy food from grocery stores, they should put it in packaging bags. If self-sealing bags are chosen, the food will last longer, and the well-sealed packaging can also prevent food contamination, so many people now use self-sealing bags to package food. This type of packaging bag has many names; it can be called a sealing bag or a self-sealing bag. When using a sealing pad, it can be reused multiple times. As long as there is a packaging bag and a sealing effect, most people will reuse the packaging bag to hold things.

What are the requirements for VCI anti-rust bag packaging?
After using rust preventive paper and VCI rust preventive bags, there is no need to apply rust preventive oil to the packaging materials. The working environment is clean, and there is no need for painting and degreasing processes, saving investment, labor costs, and a lot of time, making it more economical. Compared with vacuum packaging, rust preventive paper and rust preventive bag packaging materials are low in cost, simple in packaging method, similar in effect, environmentally friendly, and pollution-free. Rust preventive paper is simple to use, clean to pack, and convenient. So, what are the requirements for VCI rust preventive bag packaging?

What do you know about square-bottom bags?
A square-bottom bag is a bag that appears square from the outside, and its bottom is also square.
