Clear POF film may be useful when the product and label need to remain visible. Wrinkles, dust, seal placement and surface cleanliness affect appearance as well as film optics.
Sealing and shrink
Position the seal so it does not obscure important visual areas. Suitable film width and balanced tunnel settings can help reduce excess material and wrinkles.
Assess real conditions
After samples cool, inspect them from several angles under representative shelf lighting. Record label readability, scratches and potential abrasion after transport. Where food contact is intended, verify the relevant compliance documents separately.
