Plastic seal is our daily production and life are used to the goods, its strong, flexible, bending and other characteristics, so that it can be on most of the goods, equipment marked sealed. And the source of these characteristics is decided according to the plastic material that USES, so what material is common plastic seal made of?

Most of the plastic seal is PP(polypropylene) and PE (polyethylene) through proportional adjustment of the composition, PP(polypropylene) has a good stiffness can make the output of the seal has increased hardness, PE (polyethylene) join the seal has a wax-like feel and can withstand low temperature. By adjusting the proportion of PP and PE, the plastic seal can have the characteristics of two materials to increase the availability of the seal.

In addition, the plastic seal will also increase the powder used for laser, the ordinary seal without laser powder, through laser printing, out of the handwriting is very weak, so the need to add laser is also plastic seal can not material. For example, the need to add night luminescence, can be added in the plastic seal ratio of phosphor, so as to achieve the role of night luminescence.

A seal PP plastic injection molding, in sheet steel, seal product at 45 degrees below zero, plus 50 degrees not variant, surface by stamping or a laser logo, serial number, bar code, such as company logo, sealing containers when adjust at tightening, color can be made into red, blue, green, yellow, can also according to user requirements into other color, etc.

The material of plastic seal mainly depends on the user's demand, through the demand to add the nature of the material, so that the seal to a specific demand.
