embalagem de filme espumado impresso |
摘要 |
A package includes at least one layer of foamed thin film and an opening feature formed in the layer of foamed thin film. The foamed thin film has a caliper of from about 10 microns to about 250 microns thick. The foamed thin film comprises from about 5% to about 50% density reduction as compared to a non-foamed thin film of substantially the same caliper and substantially the same composition. The package may include foamed thin film made of a plastic resin and a whitening additive that is added to plastic resin. The whitening additive is selected to produce a foamed thin film having an opacity value of from about 35% to about 99%. The whitening agent is of substantially the same composition and is present in substantially the same amount as would be selected to produce substantially the same light reflectivity in a non-foamed thin film of substantially the same caliper and substantially the same composition. |
