Reasons for opacity of stretch film
1. The rubber roller or scraper is defective, which is not clean and cannot be pressed lightly, resulting in neutralization and opacity.
2. If the amount of glue is insufficient, resulting in vacant areas and small bubbles, resulting in stains or opacity, the amount of glue should be checked to make it symmetrical.
3. There is too much dust in the environmental quality, and after the release of super glue,the dust in the warm air is blown into the dry and safe passage. The adhesive on the surface of the adhesive layer is sandwiched between two base films during the whole process of the composite type, and there are many small spots, causing opacity.
4. The temperature of the channel is too high, and the drying is too fast. The organic solvent on the surface of the adhesive volatilizes and forms a ring like an extinct volcano through the stretch film, which also makes the stretch film opacity.
