Described are liners for bulk containers that are abuse resistant. The liners include at least one sidewall. The sidewall includes at least an exterior ply and an interior ply. Optionally, the sidewall may include at least one intermediate ply. One of the plies includes a first polyolefin-silicone copolymer. The adhesion between the plies is from 0 g/2.54 cm to 50 g/2.54 cm (0 g/in to 50 g/in).

Liners for bulk containers

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 medical device packaging film

An easy opening heat-shrinkable bag adapted to be heat sealed to a closed condition to contain and protect a product disposed therein, whereby, at least one heat seal is peelable and readily openable by application of force.

Easy open heat-shrinkable packaging

An easy open package adapted to be heat sealed closed and peelably reopened including a first package wall comprising an outer layer, an inner sealant layer and a tie layer disposed between and peelably bonded to either the inner layer or the outer layer and a second package wall joined about a portion of its perimeter to the first package wall and comprising at least one layer, that layer being a sealant layer having the same composition as the inner sealant layer of the first package wall and disposed adjacent thereto, the sealant layers being heat sealable together to form a bond having a bond strength greater than the bond between the tie layer and the layer to which it is peelably bonded, that bond strength being predetermined by the selection of the compositions of the adjacent layers.
