HOT MELT TAPE AND MANUFACTURING AND USING METHOD THEREOF
The present disclosure provides a hot melt tape at least including a substrate, an adhesive layer, and an anti-sticking layer, wherein the anti-sticking layer is adjacent to the adhesive layer and is the outermost layer of the hot melt tape. The hot melt tape may be used to seal objects, and preferably is made of a multilayer co-extrusion process. The anti-sticking layer prevents the hot melt tape from sticking the objects without needing a release film, and the hot melt tape can be directly heated during sealing the objects.

COMPOSITIONS AND FILMS COMPRISING POLYLACTIC ACID POLYMER, POLYVINYL ACETATE POLYMER AND PLASTICIZER
A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25 C; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.
COMPOSITIONS AND PROCESSES FOR PROVIDING RELEASE COATINGS
An aqueous composition that can be used to provide a release release properties to adhesive tape substrates can be applied at coating weights far less than those required in previously available compositions containing the same or similar release polymers. Inclusion of small amounts of a superwetter results in improved coatability and reduced amounts of sound generated during the process of releasing an adhesive tape from its roll.
Compositions and films comprising polylactic acid polymer, polyvinyl acetate polymer and plasticizer
A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.
PLASTIC FILM AND PACKAGING USING THE PLASTIC FILM
A multi ply plastic film to create a heat-sealed enclosure for food to be heated inside the enclosure save for a region of the heat-seal where a vent-opening can be established to allow gas and/or steam to escape the enclosure during heating of the food. The film has a primary panel to create the enclosure by heat sealing to itself or a separate panel or to a peripheral lip of a container There is also provided a release panel applied to said primary panel to be located intermediate of and to prevent the primary panel being heat-sealed to itself or peripheral lip at the peripheral heat-sealed region for the vent-opening to thereat be established.

Interlayer And Laminate With Controlled Debonding Zone Treatments With Enhanced Performance
The present invention relates to a laminate structure comprising an adhesive polymeric interlayer (API) that comprises discrete zones. Such discrete zones are located at the interface of the API and the glass substrate. Generally, the discrete zones comprise two sets of discrete zones, debonding and adhesive. These zones allow for a unique combination of modified API-glass debonding, laminate toughness, and laminate durability. Various spatial patterns and densities of debonding are described, as well as the resulting material properties.

AQUEOUS-BASED RELEASE COATING COMPOSITIONS
Aqueous-based release coating compositions are disclosed. The disclosed aqueous-based release coating compositions are particularly suitable for use with pressure sensitive adhesives. In some embodiments, the aqueous-basedrelease coating compositions include (A) a vinyl-based emulsion copolymer comprising a copolymerizable acid monomer, (B) asilicone-based emulsion comprising a mixture of amine-, polyol-functional siloxane and epoxy-, glycol-functional siloxane, and (C) apolymeric dispersant comprising an acid functional group. In some embodiments, the weight ratio of silicone-based emulsion (B) to polymeric dispersant (C) in the aqueous-based release coating compositions is from 2:1 to 3:1. The disclosed release coating compositions are suitable for use in, inter alia, tape applications.
