Summary
Purchase of skin film _ Skin film Important aspects considered vary across different industries. When selecting skin film, under the premise of meeting standards, try to choose varieties with relatively higher cost performance to save packaging costs, reduce expenses, and improve competitiveness.
Purchase of skin film _ Skin film Purchase considerations:
1 1. Light transmittance and haze
Light transmittance and haze are important indicators determining the visibility and clarity of the packaged product, having a significant impact on the product's display effect. Skin film The light transmittance and haze are both expressed as percentages. The higher the light transmittance value, the better the film's transparency. The greater the haze, the more turbid the object appears through the film, meaning poorer clarity.
2 2. Glossiness
Glossiness indicates Skin film the reflective ability under illumination, expressed as the percentage of the sample's brightness in the specular reflection direction relative to a standard surface reflection.
3 3. Antistatic property
With the rapid development of the electronics industry, the integration level of electronic circuit boards is increasing, Skin film packaging products can prevent static damage to integrated circuits.
4 4. Good smoothness
Good smoothness facilitates Skin film smooth movement on the packaging production line, preventing damage caused by excessive resistance during movement. Skin film The smoothness can be described by its coefficient of friction; the smaller the coefficient, the better the smoothness performance.
5 5. High-temperature resistance
Often considered is Skin film the high and low temperature resistance of the film. For example, for refrigerated and especially frozen foods, the skin film needs to have good low-temperature resistance; for steamed foods, the skin film needs to have good high-temperature resistance, etc.
6 6. Hygiene performance
When packaging food or pharmaceuticals, the selected Skin film film must have good hygiene performance, meeting relevant hygiene standards to ensure the skin film does not contaminate the packaged goods.
7 7. Airtightness
Skin film Good airtightness must be ensured to significantly block the exchange of gases inside and outside the packaging container.
8 8. Moisture resistance
Good moisture resistance is an important means to protect products. Generally, Skin film the moisture resistance of the film increases with thickness and decreases with temperature.
9 9. Oil resistance
For oily foods such as sausages and cured meats, the Skin film film must be oil-resistant; otherwise, it will affect product quality.
