Abstract: A substrate composite film for thermal transfer printing includes a biaxially oriented base layer including polyester, a first type of lubricant particles, and a second type of lubricant particles. The substrate composite film satisfies the following: (1) a ratio of maximum height SRma and peak count SPc is 1?SRma/SPc?4.5, (2) a center plane average roughness Sra is 15 to 30 nm, (3) coefficient of dynamic friction is <0.60, and (4) 20 and 60 degree gloss is greater than 160 SGU. The 20 degree gloss may be equal in all directions, and the 60 degree gloss may be equal in all directions.

Abstract: Described are stretchable and formable lighter than air balloons including a high barrier lamination. The stretchable and formable balloons stretch when overinflated instead of failing. The balloons are formed from a lamination including a polyester film with a total thickness of 4 ?m to 12 ?m including a biaxially oriented polyester core layer and at least one amorphous copolyester skin layer. The polyester film has an Elongation % in the transverse direction (TD) or machine direction (MD) of greater than 125%.

Abstract: Described are methods for recycling biaxially oriented thermoplastic crystallizable films, such as polyester terephthalate (PET) films, that have been coated with various polymers or waxes that are immiscible in the primary molten thermoplastic. The resultant processed recycle can be used to make new biaxially oriented thermoplastic films while avoiding process instability and optical defects in the finished film associated with immiscible polymeric and/or wax coatings.

Abstract: Described are methods for producing a sequentially biaxially oriented thermoplastic film having balanced machine direction (MD) and transverse direction (TD) heat shrinkage properties. The methods can include extruding a film, orienting the extruded film in a machine direction, quenching the film, heating the film in an transverse orientation oven and transversely orienting the film, and allowing the film to relax in the machine direction at a machine direction tension lower than a machine direction tension of the film in the transverse orientation oven.

Abstract: A biaxially oriented laminated polyester film (10) for transfer applications having a total thickness of from about 2.0 to about 7.0 um, comprising at least a first polyester layer (A layer) (12) forming on one side (A side) a first surface and a second layer (B layer) (16) forming on the other side (B side) a second surface, wherein the A side surface has a first surface roughness and the B side surface has a second surface roughness that is greater than the A side surface roughness.
