Product Description

Mylar® P25 is an uncoated, transparent polyester packaging film designed to be combined with a sealant layer, where the resulting structure will be shallow draw thermoformed. Standard thicknesses are 50 and 75 gauge, although other thicknesses may be available upon special request. All gauges can be supplied with a corona surface treatment, as P25T, for improved bonding to inks and adhesives. 

General Product Info

The 50 gauge film can be formed to a maximum draw depth of 1 1/8 in (28 mm), where the draw ratio (area/area) does not exceed 2.0. The 75 gauge P25 can be thermoformed to a maximum draw depth of 1 1/2 in (38 mm) with a maximum draw ratio of 2.25. Good temperature control is essential for satisfactory thermoforming. Observation of excessive web thinning and/or frequent “poppers” during thermoforming usually indicate that the forming temperature should be increased.
