摘要:
Provided are an adhesive sheet for a tire, which has a small ratio of dimensional change with the passage of storage time or the like even in a case in which a polyolefin-based resin film is used as a substrate; and a method for manufacturing an adhesive sheet for a tire. Disclosed is an adhesive sheet for a tire, the adhesive sheet including a substrate and an adhesive layer, and the adhesive layer containing a hot melt type adhesive composition, characterized in that the ratio of dimensional change in the MD direction of the adhesive sheet for a tire measured for 7 days at 60°C according to JIS K 7133 has a value of below ±0.6%, the substrate is a polyolefin-based resin film, the hot melt type adhesive composition includes the following components (A) to (C): (A) a block copolymer: 15% to 40% by weight; (B) plural tackifiers having different softening points: 30% to 70% by weight; and (C) a liquid hydrocarbon-based plasticizer: 10% to 50% by weight, and the number average molecular weight of the (C) liquid hydrocarbon-based plasticizer has a value within the range of 10,000 to 60,000.

摘要:
A web for forming sealed air filled pouches includes a plurality of fold seals that seal first and second elongated layers together along a fold area defining first and second chambers. The fold seals create a cushioned area along a fold area when the first chamber is folded over the second chamber. Also disclosed is a device for separating air filled pouches. The device includes a first stage including a first belt operating at a first speed and a second stage including a second belt operating at a second speed. The web passes through the first stage before passing through the second stage. A pouch is separated from the web at the lines of perforations when a relative speed of the first belt is slower than a speed of the second belt by a predetermined threshold.
摘要:
There is provided a package material comprising an oxygen barrier polymer film, wherein the film comprises a polymer obtainable by a process comprising the steps of: a) oxidising cellulose fibers to ultimately obtain cross-linked cellulose; and b) homogenising the product of step a) to obtain fibrils in a width range of 1 nm to 150 nm. A corresponding use is also provided.
摘要:
Disclosed is an encapsulation barrier stack, capable of encapsulating a moisture and/or oxygen sensitive article and comprising a film layer with at least one layer, wherein the film layer comprises: one or more nanoparticle sealing layer(s) arranged to be in contact with surface of the at least one substrate, wherein the substrate is not a barrier layer, wherein the one or more nano-particle sealing layer(s) comprise(s) a plurality of encapsulated nanoparticles, the nanoparticles being reactive in that they are capable of interacting with moisture and/or oxygen to retard the permeation of moisture and/or oxygen.
