Our lives are improving more and more, and so is the popularity of selecting products from websites. When making purchases, we inevitably use a product called packaging material. Today, Xinping Packaging Material is here to introduce the issues that may arise during the production of foam packaging materials and how to resolve them.

Single yarn surface roughness

1. The extrusion temperature is too low; the mold and body temperatures should be appropriately increased.

2. The extrusion die was not clean; the machine was disassembled for cleaning the die holes.

Issue 3: Poor hole cleanliness in the spinneret, correct or replace the spinneret plate.

The water temperature in the cooling tank is too high; it should be reduced.

Two, single fiber strength variance

The EPE factory may encounter some unsuitable raw materials, therefore, a reselection of raw materials is necessary.

2. The body temperature and nozzle temperature are too high. The body and nozzle temperatures should be appropriately reduced.

3. The hot water temperature is low; it should be increased.

4. Low elongation ratio; appropriately increase the elongation ratio.

During the production of polyethylene foam, inconsistencies in the thickness of individual filaments were observed.

1. Inconsistent nozzle hole sizes or clogged holes require trimming, cleaning, or adjusting to replace the die plate.

2. If the draw roller or transmission belt slips, the equipment should be properly inspected and maintained.

3. Inconsistent dispersion of stabilizers and lubricants. Enhance the kneading operation.

Four: Bubbles on the surface of the single silk

High moisture content in raw materials requires preliminary drying treatment.

2. The temperature was too high, causing decomposition; it is advisable to lower the temperature for stability.
