LABELS OF LAMINATED PAPER WITH SHRINKABLE OR NON-SHRINKABLE POLYMERIC FILM
A self-adhesive label includes a bilayer having at least one layer of paper coupled to at least one polymeric film, wherein the polymeric film is coated, on the surface opposite to the surface of coupling to the at least one paper layer, with a layer of pressure sensitive adhesive (PSA). The adhesive has wash-off properties such as to cause the label to peel off from a surface by washing with a 1.0%-2.0% NaOH solution at 65-75? C. Alternatively, the adhesive has a force lower than the shrink force of the polymeric film. The label also includes an intermediate layer placed between the polymeric film and the PSA adhesive, capable of promoting the adhesion of the PSA adhesive to the polymeric film, and/or the polymeric film is treated with a corona, flame treatment or plasma treatment.
COMPOSITE TEXTILE FABRICS
A composite textile fabric that includes a first (face) fabric layer, and a second (back) fabric layer that is formed concurrently with the first fabric layer in a plaited construction. The second fabric includes a plurality of anchored regions at which the second fabric layer is anchored to, and in intimate contact with, the first fabric layer. The second fabric layer also includes a plurality of floating regions, overlying and unattached to the first fabric layer, interspersed between the anchored regions.
Polyester film having latent shrink properties and process for producing same
A film layer is disclosed that is capable of shrinking when subjected to energy, such as heat. The film layer, for instance, can be formed and then stretched in one or two directions at a relatively low temperature. In particular, the film is stretched while the film layer is at a temperature near the glass transition temperature of the polymer used to form the film. Drawing the film at a relatively low temperature has been found to improve the shrink properties of the film. In one embodiment, the film layer is comprised of a non-modified polyester, such as polyethylene terephthalate. For example, the polyethylene terephthalate can be made by reacting terephthalic acid with ethylene glycol or polyethylene glycol.
BASE MATERIAL FOR METAMATERIAL, METAMATERIAL, LAMINATE, AND MANUFACTURING METHOD OF METAMATERIAL
Provided are a base material for a metamaterial, in which a thermal dimensional change rate in a case of being allowed to stand in an environment of 90 C. for 24 hours is 0.01% or more and less than 10%; a metamaterial and a laminate including the base material for a metamaterial; and a manufacturing method of a metamaterial.
MULTILAYER FILM, MULTILAYER BODY AND PACKAGE
There are vapor-deposited films exhibiting various heat shrinkable properties depending on the base film. In a case where a laminate product is fabricated using a vapor-deposited film having a high heat shrinkage rate in the machine direction and subjected to retorting, the barrier properties may deteriorate. Improvement using base films has the disadvantage that a special brand is required to be established since the production quantity at one time is large. The water vapor transmission rate after retorting can be suppressed to 2.5 g/m.sup.2.Math.day or less by providing a laminated body having a shrinkage rate in the MD direction before and after retorting of 1.2% or less in the transverse direction and a difference between the maximum MD shrinkage rate and the minimum MD shrinkage rate in the transverse direction of 0.4% or less.
RESIN LAMINATE FOR PACKAGING MATERIAL
An object of the invention is to provide a resin laminate for packaging material containing a base layer and a sealant layer, each of which contains the same material with high processability. The resin laminate for packaging material contains at least a base layer and a sealant layer, wherein each of resin compositions for the base layer and the sealant layer contains the same resin (A) as a main component, the base layer has a fusion initiation temperature (FIT-B), and the sealant layer has a sealing initiation temperature (SIT-S), wherein the temperatures satisfy the following inequalities of from (1) to (3):
50 C.(FIT-B)(SIT-S)90 C. Inequality (1)
90 C.(SIT-S)120 C. Inequality (2)
160 C.(FIT-B)180 C. Inequality (3).

LAMINATE AND METHOD OF MAKING SAME
A laminate is made by first making by melt-blowing or spunbonding of multicomponent, thermoplastic, and endless filaments a first nonwoven layer lying generally in a plane and having a predetermined shrinkage capacity or potential parallel to the plane and making of thermoplastic and endless filaments a second nonwoven layer also lying generally in a respective plane and having a shrinkage capacity or potential that is smaller than that of the first nonwoven layer. The two layers are directly juxtaposed flatly on each other, and the directly juxtaposed first and second layer are bonded together only at bonded regions while leaving an array of unbonded regions distributed over a surface of the two bonded-together nonwoven layers. Then only the first nonwoven layer is shrunk so that the second layer bunches in the unbonded regions and is there raised transverse to a plane of the bonded-together layers.
Cover plate for aircraft door
A cover plate, to cover part of a space between a door and a door surround, comprising at least one pressure element secured to at least part of the external face of the cover plate. The pressure element comprises two sheets, an external sheet and an internal sheet, these two sheets being superposed and fixed together. The internal and external sheets are respectively made from materials that have different thermal expansion properties causing at least a contraction of the internal sheet with respect to the external sheet, at least for a range of temperatures comprised between 20 C. and 50 C.
Heat-shrinkable film and heat-shrinkable label
What is provided is a heat-shrinkable film and a heat-shrinkable label that, when applied to a container in which the difference between the diameter of the body portion and the diameter of the mouth portion is large, sufficiently shrink in the mouth portion and do not easily allow the generation of a wrinkle or a sink mark in the mouth portion. The heat-shrinkable film contains polyester, a dicarboxylic acid component that constitutes the polyester contains 95 mol % or more of terephthalic acid, and a diol component that constitutes the polyester contains 50 mol % or more of ethylene glycol and 15 mol % or more of cyclohexanedimethanol. The shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 70 C. for 30 seconds is 20% or less, the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 80 C. for 30 seconds is 45% to 65%, and the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 98 C. for 30 seconds is 65% or more.
