The present invention provides solvent-based compostable cold seal release lacquers for use in packaging structures. The lacquers of the invention comprise resins, such as polyamide resins, comprising greater than 90% biobased carbon, generally prepared from renewable sources, e.g., plants such as rice. The present invention also provides the use of the inventive compostable lacquers as cold seal release lacquers in cold seal packaging, along with eco-friendly packaging film, etc., and has the potential to make the cold seal packaging fully compostable.

A packaging material can include cold seal adhesive on a first side of a substrate, glossy material on a second side of the substrate, and matte material on the glossy material, so that the matte material covers at least a predetermined portion of the glossy material. Each of the glossy and matte materials can be a cold seal release lacquer configured so that when the packaging material is formed into a roll, the cold seal adhesive is releasably adhered to the cold seal release lacquers, the glossy cold seal release lacquer is fixedly adhered to the substrate, and the matte cold seal release lacquer is fixedly cohered to the glossy cold seal release lacquer.

Polymeric multilayer film having first and second opposed major surfaces, comprising at least one layer comprising a first release agent and exhibiting a random network of strands and connective regions. The polymeric multilayer films are useful, for example, for tape and graphic articles.

A roll of a double-sided adhesive tape wound around a core, with the tape (10) comprising first (5) and second major adhesive surfaces (4) and at least one adhesive layer comprising a structural adhesive (3) providing the second major adhesive surface (4). The first major adhesive surface (5) is protected by a first liner (1); the second major adhesive surface (4) is protected by a second liner (2), and the second liner (2) extends over the two edges (8, 9) of the second major surface to cover at least part of each first and second minor surfaces (6, 7) of the tape (10).
