Plastic lead seals have become a powerful tool for commodity management. As theft incidents are increasing, people attach great importance to disposable lead seals. But in the face of a variety of lead seals, many buyers are confused, because these lead seals are either extremely expensive or unsatisfactory quality. Then, how can we pick out the safe, easy-to-use, solid and durable plastic lead seal? Shandong Junchuang Lock Industry Xiaobian prompts you to focus on the following key points:

Look at the material

The plastic lead sealing materials on the market are basically divided into PP, PE, nylon and so on. PP: polypropylene, translucent, melting point in production is 220-320 degrees, only PP has no feel, and will break for a long time; PE: polyethylene, translucent, only PE fold will not produce white print, but too soft, small pulling force, easy to draw silk; Nylon: nylon 66 is expensive, one fold will not produce white print, poor volume production, strict requirements; Optimum: PP + PE, can increase hardness and softness, our company production. The plastic lead sealing material is PP+PE.

Look at surface treatment

Generally, there are three kinds of surface treatment: electroplating, spraying and coloring. Through these surface treatment, a protective film can be formed on the product, which can prevent corrosion and rust. At the same time, it can make the product more beautiful and durable. It can directly measure the quality of the product. Locks with good quality are usually treated by electroplating. The coatings are moderate, uniform and bright in color. There are no signs of bubbles, rust and oxidation.

Look at functional design and key components

There are many kinds of locks. The choice of locks depends on where they are used. Large brands with high quality requirements have very detailed product classification for different functional requirements.
