MYLAR® M34

Product Description

Mylar® M34 is a transparent, polyester packaging film, solvent coated on one side with a PVdC copolymer. The coating is heat sealable and is an excellent moisture and oxygen barrier. M34 is available in 50, 75 and 100 gauge with the coated side normally wound toward the core.

General Product Info

Mylar® M34 can be surface or reverse printed with appropriately formulated inks, and can be combined with other webs by adhesive or extrusion laminating. When printing and adhesive laminating on the coated surface, active solvents such as acetates, ketones and toluene should be removed as completely as possible during drying to avoid adverse effects on coating adhesion. Slow evaporating solvents, such as glycol ethers, should be avoided completely.

High temperature heat sealing of polymer-coated Mylar® M34 may release small amounts of irritating fumes which should be removed by using area ventilation.

Typical Applications

Mylar® M34 was designed to be reverse printed on the coated side, then combined with a sealant layer such as polyethylene or Surlyn® resin - locking in the PVdC coating. Such a structure is quite durable, and its sparkling clarity and excellent barrier properties, plus its resistance to heat and humidity, make this an ideal combination for gas and vacuum packaging of processed meats and cheese.
