Description

1、 Introduction

In modern packaging industry, the sealing machine is a key packaging equipment, and its performance directly affects the sealing quality and production efficiency of products. As the core components of sealing machines, Teflon tape and Teflon adhesive tape play an irreplaceable role in the packaging field due to their excellent performance. This article will delve into the application characteristics, advantages, and selection points of these two materials in sealing machines.

2、 Characteristics of Teflon materials

Teflon is the trademark name for polytetrafluoroethylene (PTFE), which has the following prominent characteristics:

1） * * Excellent temperature resistance * *: Can work for a long time in the temperature range of -70 ℃ to 260 ℃

2） * * Extremely low friction coefficient * *: Smooth surface with a friction coefficient of only 0.04-0.1

3） * * Excellent chemical stability * *: resistant to strong acids, strong bases, and various organic solvents

4） * * Good non stick * *: Almost does not adhere to any substance

5） * * Excellent electrical insulation * *: high dielectric strength and stable dielectric constant

These characteristics make Teflon an ideal choice for heat sealing components in sealing machines.

3、 Application of Teflon tape in sealing machine

1） Structure and types of PTFE tapes

Teflon belts are usually made of glass fiber cloth impregnated with Teflon lotion and sintered at high temperature, mainly including:

-Pure PTFE tape

-Thick PTFE tape

-Reinforced PTFE tape (with Kevlar fiber and other reinforcing materials sandwiched in the middle)

2）Specific applications in sealing machines

(1) * * Protection of heat sealing area * *: Wrap the heating element of the sealing machine to prevent the adhesion of packaging materials

(2) * * Conveyor Belt Application * *: Used for conveying packaging materials in high temperature environments

(3) * * Isolation layer * *: serves as an isolation medium between the heating plate and the packaging material

4. Application advantages

**Easy to install * *: Ready to stick and use, no need for professional tools

*Economically efficient * *: The cost of partial replacement is lower than that of overall replacement

**Strong flexibility * *: can cut shapes and sizes according to needs

**Easy maintenance * *: can be easily peeled off and replaced after aging

5、Selection and usage precautions

1）Key selection points

**Temperature requirement * *: Select the appropriate temperature resistance level based on the sealing temperature

**Thickness selection * *: For general sealing applications, a thickness of 0.13-0.25mm is selected

**Width matching * *: should be slightly wider than the actual contact surface

**Adhesive requirement * *: Silicone adhesive tape is preferred for high temperature environments

2）Precautions for use

**Surface cleaning * *: Ensure that the substrate surface is clean and dry before pasting

**Uniform pressure * *: When pasting, it is necessary to apply even pressure to eliminate bubbles

**Gradual heating * *: The initial use should gradually raise the temperature to the working temperature

**Regular inspection * *: Regularly check for wear and aging
