A heat-shrinkable film containing a homogeneous ethylene/alpha-olefin copolymer has a high impact strength and a high free shrink. The film can be a monolayer film or multilayer film, with the homogeneous ethylene/alpha-olefin copolymer present alone or in a blend, and in one or more film layers. Th

A heat-shrinkable film containing a homogeneous ethylene/alpha-olefin copolymer has a high impact strength and a high free shrink. The film can be a monolayer film or multilayer film, with the homogeneous ethylene/alpha-olefin copolymer present alone or in a blend, and in one or more film layers. The film is especially suited for use in heat-shrinkable bags, which can be used for the packaging of various products, especially meat.

A method as in claim 1, comprising the further step of automatically maintaining a desired flow ratio between the first and second fluids so as to maintain the desired physical and chemical properties of the blended gaseous mixture. 3. A method as in claim 2, wherein the step of automatically maintaining a desired flow ratio between the first and second fluids comprises the sub-steps of: measuring a flow rate of the first fluid; measuring a flow rate of the second fluid; measuring a change in pressure inside the distribution header; and adjusting the flow rates of the first and second fluids at the desired flow ratio proportionally in an inverse relation to the measured change in pressure inside the distribution header. 4. A method as in claim 1, comprising the further steps of: supplying a third fluid which does not react with the first or second fluids or with the blended gaseous mixture; heating the third fluid to a temperature sufficient to avoid condensation of the blended gaseous mixture delivered to the at least one tool; and combining an amount of the heated third fluid in a gaseous phase with the blended gaseous mixture whereby a desired molar ratio of the first and second fluids is maintained so as to maintain the desired physical and chemical properties of the blended gaseous mixture and whereby condensation of the blended gaseous mixture is avoided in the distribution header. 5. A method as in claim 4, comprising the further step of automatically maintaining a desired flow ratio between the first and second fluids so as to maintain the desired physical and chemical properties of the blended gaseous mixture. 6. A method claim as in claim 4, wherein the third fluid is an inert gas. 7. A method as in claim 1, further comprising the steps of: providing a storage buffer upstream of the distribution header; delivering the blended gaseous mixture to the storage buffer prior to delivering the blended gaseous mixture to the distribution header. 8. A method as in claim 1, wherein the first fluid is trichlorosilane and the second fluid is hydrogen. -567. dhesive composition comprising two or more essentially excretable, essentially non-degradable polymer backbones, wherein the polymer backbones are crosslinked, said crosslink being degradable in a mammal, said cross-linked bioadhesive composition having an average bioadhesion factor showing bioadhesion equivalent to at least about 100 g s. The concept is to build a hydrogel that demonstrates bioadhesion to a mucosal surface that is crosslinked by a degradable linkage such as disulfide for use inside the body.
