Abstract: The invention is also directed to a coextruded film comprising a core layer which comprises between 20 wt. % and 99 wt % znLLDPE or HDPE, wherein the core layer further comprises filler materials; and outer layers on each side of the core layer comprising between 50 and 99 wt % of one of LLDPE, LDPE, blends of LLDPE and LDPE, or mLLDPE; wherein the film contains relatively opaque embossed regions and relatively clear unembossed regions, wherein the opaque embossed regions comprise embossment-induced cavities and the filler materials.

Abstract: A package for storing perishable goods. Film forming the package has an inner layer that defines an interior surface of the package and is formed from a polyethylene and a tack agent that has migrated to the interior surface to provide tackiness. The tackiness permits cold resealing of the package after it has been opened, without substantially adhering to the perishable goods so that the perishable goods can be non-destructively removed from the package. An outer layer of the film defines an exterior surface of the package and is formed from another polyethylene. The polyethylene of the outer layer is configured to block migration of the tack agent through the outer layer such that the exterior surface is substantially non-tacky.

Abstract: A plastic bag comprising two panels and a flap joined to one of the panels and configured for folding over the other of the panels for closure of the bag, wherein at least a portion of the flap has a tackiness which is greater than the tackiness of its associated panel. A stack of bags having a flap with greater tackiness than the tackiness of the major panels of the bags.

Abstract: A temporary adhesive band provides a releasable sealing structure and a tearing structure in a plastic bag. The band can be coextruded with one or more panels of the bag and can be made from a polymer blend. It can have a relatively thick tear section that defines a tear line at a zone of weakness in the bag so that a closed end of the bag can be easily removed. The band also can have a releasable sealing section that remains attached to the bag after the closed end of the bag has been removed by tearing the bag along the tear line so that the bag can be resealed once it has been opened. The releasable sealing section of the temporary adhesive band is preferably made from a coextruded material with tacky properties so that no additional adhesive is required for resealing the bag.

Abstract: A plastic bag comprising a grip strip configured to assist with opening the bag, wherein the grip strip is formed from a material different from a material from which its associated panel is formed.

Abstract: An envelope has an envelope body formed by opposing panels that define an interior and an opening. A closure is joined to and extends up from the top margin of one panel. The envelope is configured such that the interior surface of the closure is sealable to the other panel to permanently close the envelope opening. The closure includes a closure panel and a tear band coextruded with the closure panel. The tear band is composed of a polymeric material having lower tear strength than the material of the closure panel. The tear band defines a zone of weakness extending along the width of the closure for opening the closure by tearing along the zone of weakness after it is permanently closed.

Abstract: The present invention generally relates to disposable gloves, ethylene-based thermoplastic materials for use in preparing disposable gloves, and methods for preparing ethylene-based thermoplastic materials for use in preparing disposable gloves. In particular, the present invention relates to non-medical and non-surgical disposable gloves suitable for use in food-service and industrial applications.
