Think thermoplastic film available in a variety of forms and finishes.
PVC is a heat shrink film and will shrink at very low heat temperature. Flexible before it shrinks onto the product. Ideal for food manufacturers or processing plants. It is the number one choice for food suppliers needing to shrink wrap fruit baskets because of its FDA compliance for indirect food contact.
Manufacturers prefer PVC shrink film because it improves shelf life and is less likely to experience problems with blocking from unintended exposure to heat or sunlight.
