Detailed Introduction of Disposable Plastic Seals

1. Structural Features and Application Scenarios

Disposable plastic seals are mainly made of synthetic resins that are injection molded in one step. They may contain some thin small steel sheets inside to enhance their strength and durability. The design of these seals allows them to maintain their shape under extreme temperature conditions. Specifically, they can operate stably between -45 to -50 degrees Celsius and between 50 to 30 degrees Celsius, although this is also influenced by the quality of the product.1

The Basic Structure and Function of Disposable Plastic Seals

The disposable plastic seal is composed mainly of the head, the long strip body, and the tail. The head is designed with a reverse hook, and the tail is equipped with a plug hole, which contains a protrusion that engages with the reverse hook of the head. This design allows the seal to be securely fastened simply by inserting the tail into the plug hole, effectively preventing others from casually disassembling, serving a security purpose.1。

3. Materials and Performance Features

• MaterialDisposable plastic seals are typically made from high-quality PP materials, which have good fire-retardant properties (such as 94V—2), excellent insulation, low susceptibility to aging, strong resistance to acids and corrosion, and good toughness.3。
• environment-friendlyPlastic seals are easy to dispose of after use and will not pollute the environment.2。
