Introduction to Plastic Seals Applied to Fire Extinguishers

Plastic seals applied to fire extinguishers are important safety devices used to ensure that fire extinguishers remain sealed and intact when not in use. These seals are typically used to prevent unauthorized use or tampering, ensuring that the fire extinguisher functions properly in an emergency. The following is a detailed introduction to plastic seals for fire extinguishers:

1. Definition and Usage

Definition: A plastic seal for a fire extinguisher is a seal made from plastic material, used to secure the handle or nozzle of a fire extinguisher, ensuring it remains sealed until needed.

Usage: Primarily used to prevent unauthorized use or tampering, ensuring that the fire extinguisher is ready for use in an emergency.

2. Materials and Structure

Materials: Typically made from high-strength plastic materials such as polypropylene (PP) or polyethylene (PE), which have good weather resistance and anti-aging properties.

Structure: The seal usually consists of two parts: the main body of the seal and the locking part. The main body passes through the handle or nozzle of the fire extinguisher and is then secured with the locking part, forming an irreversible seal.

3. Features

Tamper-Evident: Once the seal is applied, it cannot be removed without leaving obvious signs of tampering.

High Visibility: The seal can be printed with company logos, numbers, barcodes, etc., for easy management and tracking.

Weather Resistance: Performs well under various environmental conditions (such as high temperatures, low temperatures, and humidity).

Easy Installation: The installation process is simple and quick, typically involving passing the seal through the handle or nozzle and securing it with the locking part.

Cost-Effective: Compared to metal seals, plastic seals are less expensive and suitable for large-scale use
