The present disclosure relates to flexible, multilayered packaging films and packages produced from the films. In particular, the films include a machine direction linear tear layer that comprises from 60 percent to 95 percent ethylene vinyl alcohol copolymer (EVOH) and from 5 percent to 40 percent polyethylene. The films and packages demonstrate improved machine directional linear tear.

Directional tear packaging film

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

Product packaging with heat sealable barrier material

Compositions and methods for generating ClOgas are disclosed. A composition that includes a chlorite salt is activated by exposure to ultraviolet light. After an optional storage period, the composition is then exposed to moisture, resulting in the generation of ClOgas. Exemplary compositions include polymers in which the chlorite salt is dispersed. The polymers may be used to form films that can be used to package, e.g., food products, pharmaceutical products, medical devices, and/or laboratory devices. Upon exposure to ultraviolet light and moisture, the packaging releases controlled quantities of ClOgas, which may disinfect and/or deodorize the packaged device or product.

Methods and compositions for on-demand release of ClOgas from UV-activated chlorite ion

A multilayer produce packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

Release of ClOgas from produce packaging film

A lidding film to use in food packaging, or the packaging of suitable non-food products, includes a substrate having an outer major surface on which is disposed at least a 5 heat-sealing layer (HS layer), a non-heat-sealing layer (NTIS layer), and a hydrophobic coating. On a side of the lidding film that corresponds to the outer major surface of the substrate is a peripheral region that encircles a central region. At least a first portion of the HS layer fills the peripheral region, and the NIS layer is absent as a cover on, or does not cover, the HIS layer in the peripheral region. At least a first portion of the NHS layer fills the 10 central region, and the HS layer is absent as a cover on, or does not cover, the NIS layer in the central region.

Heat-seal lid with non-heat sealing layer and hydrophobic overcoat

A multilayer medical packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

Described are liners for bulk containers such as intermediate bulk containers (IBC) that are abuse-resistant and barrier-providing. The liners have at least one sidewall that is multi-plied and the plies are multi-layered. The liners are preferably metal-free. Each ply independently comprises at least three layers that comprise: a first layer and a third layer each comprising a linear low density polyethylene (LLDPE) or a very low density polyethylene (VLDPE); and a second layer between the first and third layers and comprising a thermoplastic oxygen barrier of ethylene-vinyl alcohol copolymer (EVOH) and a thermoplastic elastomer (TPE). A ply may further comprise a fourth layer and a fifth layer, each comprising a polyamide, the fourth layer being located between the first and second layers and the fifth layer being located between the second and third layers. Methods of making and using the liners are also provided.

Liners for bulk containers

Food packaging articles, food packaging webs, and food packaging methods comprising a myoglobin blooming agent and synergist that promote or preserve the desirable appearance of food products are provided. The food contact layer of the packaging webs may comprise a myoglobin blooming agent and a synergist.

Webs with synergists that promote or preserve the desirable color of meat

Non-shrink, forming and nonforming thermoplastic webs comprising a myoglobin blooming agent on a food contact surface are useful for packaging fresh meat and other products to fix a desirable color on the surface of the product.

Myoglobin blooming agents, films, packages and methods for packaging

Heat shrinkable, oxygen barrier, packaging films, methods of packaging and packages are provided having a myoglobin blooming agent to provide, promote, enhance or maintain a desirable coloration on the surface of a myoglobin-containing meat product.

Myoglobin blooming agent containing shrink films, packages and methods for packaging

A process includes introducing a base polymer into an extruder, heating to a temperature sufficient to form a polymer melt, introducing a liquid comprising water and at least one additive consisting of an NO donating compound with mixing and subsequent vaporization and venting of the liquid to produce an extrudate having a uniform distribution of preferably uniformly small additive particles.

Process for introducing an additive into a polymer melt

Food packaging articles, food packaging films, and food packaging methods comprising a myoglobin blooming agent that promote or preserve the desirable appearance of food products are provided. The food contact layer of the packaging films comprises a myoglobin blooming agent.

Packaging articles, films and methods that promote or preserve the desirable color of meat

A method of distributing or commercializing fresh meat having the general steps of butchering a slaughtered animal into a plurality of retail cuts; packaging the retail cuts into a plurality of articles wherein each article comprises a polymeric oxygen barrier film having a transparent portion in contact with at least a portion of the fresh meat product; transporting the packaged article to a retail outlet, wherein the packaged article is adapted for retail display and sale without removing the polymeric film and wherein the fresh meat product has a desirable appearance especially a desirable red color e.g. having an 'a*' value of at least about 15 for the fresh beef product or of at least about 6 for a fresh pork or fresh poultry product and the color is maintained for at least five days and up to four weeks or more after display.

Method for distributing a myoglobin-containing food product

The present invention describes thermoformable coextruded film suitable for use in packaging applications having at least a first polymeric layer serving as an outermost exterior-film layer and comprising a cycloaliphatic polyester, an aromatic polyester or blends thereof; a second polymeric layer serving as a thermoforming-assist layer and comprising a polyolefin; and a third polymeric layer serving as an innermost exterior-film layer and comprising a heat-sealing polyolefin material. The films of the present invention are oxygen-permeable in that they exhibit an oxygen transmission rate of between 32-1000 cm/100 in/24 h. atm.
