Product Description: Perforated and non-perforated shrink nylons are heat-sensitive flexible packaging materials used in packaging products. The perforated version is ideal for products that require ventilation and allows the products to breathe. The non-perforated version offers completely closed protection and isolates the products from external factors. Both types ensure that products are properly wrapped, secured and transported safely. When heat is applied, it shrinks and takes the shape of the product and wraps it tightly.
