Product DescriptionMylar® 850AF is a biaxially oriented, co-extruded polyester film with a layer of amorphous heat-sealable polyester film on one surface and plain polyester on the other. Mylar® 850AF is ideal for chilled applications where strong, permanent seals with good ‘seal through contamination’ properties are required. Mylar® 850AF can be heat-sealed to itself, APET/CPET trays, APET coated board, PVdC, PVC, paper and aluminium foil, but not to polyolefins. Excellent ‘hot-tack’ sealing properties can be achieved in the sealing range of 140°C to 220°C.
- Anti-fog properties are ideal for chilled applications
- Excellent barrier properties, make it suitable for aromatic products
- Dual ovenability across a wide temperature range
- Strong, tamper-evident seals
