Laminate body and packaging bag using the same
A laminated body having at least two or more different layers, wherein the laminate body is characterized by satisfying the following requirements (1) to (5): (1) the laminate body has a heat-sealing layer as at least one of the outermost layers, wherein the heat-sealing layer includes a polyester based component containing ethylene terephthalate as a main constituent component, and a sealing strength of 8 N/15 mm to 30 N/15 mm; (2) at least one layer other than the heat-sealing layer is an inorganic thin film layer; (3) a water vapor permeation rate of 0.1 g/m.sup.2.Math.d to 6 g/m.sup.2.Math.d; (4) an oxygen permeation rate of 5 ml/m.sup.2.Math.d.Math.MPa to 30 ml/m.sup.2.Math.d.Math.MPa; and (5) a heat shrinkage rate of −5% to 5%.
Films including a water-soluble layer and a vapor-deposited inorganic coating
Methods for making films including a water-soluble polymeric material and a vapor-deposited inorganic coating are disclosed. The method comprises providing a layer of water-soluble polymeric material and vapor depositing an inorganic coating to at least one surface of the layer of water-soluble polymeric material, wherein the inorganic coating comprises a metal oxide. The method further comprises forming a plurality of microfractures extending along the surface of the inorganic coating.
Sealing film suitable for food packaging and preparation method thereof
A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

The vapor-deposited inorganic coating may include a metal oxide. The vapor-deposited inorganic coating may include a plurality of microfractures. The films may form part of a package and/or a water-soluble unit dose article.
FILMS INCLUDING A WATER-SOLUBLE LAYER AND A VAPOR-DEPOSITED INORGANIC COATING
Methods for making films including a water-soluble polymeric material and a vapor-deposited inorganic coating are disclosed. The method comprises providing a layer of water-soluble polymeric material and vapor depositing an inorganic coating to at least one surface of the layer of water-soluble polymeric material, wherein the inorganic coating comprises a metal oxide. The method further comprises forming a plurality of microfractures extending along the surface of the inorganic coating.
Improvements To Gloves And A Method of Manufacture
A glove of a type worn to provide masking effect between a wear's hand and another surface, such as surface of food stuff. The glove, or fragments thereof, is rendered detectable by X-ray and/or metal detection apparatus. Apparatus and/or indication means can be provided to allow a detected glove or glove portion to be allocated to a particular location and/or personnel to allow, if necessary, remedial action to be taken.
LAMINATE BODY AND PACKAGING BAG USING THE SAME
A laminated body having at least two or more different layers, wherein the laminate body is characterized by satisfying the following requirements (1) to (5): (1) the laminate body has a heat-sealing layer as at least one of the outermost layers, wherein the heat-sealing layer includes a polyester based component containing ethylene terephthalate as a main constituent component, and a sealing strength of 8 N/15 mm to 30 N/15 mm; (2) at least one layer other than the heat-sealing layer is an inorganic thin film layer; (3) a water vapor permeation rate of 0.1 g/m.sup.2.Math.d to 6 g/m.sup.2.Math.d; (4) an oxygen permeation rate of 5 ml/m.sup.2.Math.d.Math.MPa to 30 ml/m.sup.2.Math.d.Math.MPa; and (5) a heat shrinkage rate of 5% to 5%.
Composite Packaging Foil
A composite packaging foil for a childproof and/or senior friendly packaging, including a first layer having a first outer surface and a first inner surface, wherein the first layer imparts tear-inhibiting properties to the packaging foil, a second layer having a second outer surface and a second inner surface, wherein the second outer surface of the second layer is sealable against a mating surface, an inner layer arranged between the first inner surface of the first layer and the second inner surface of the second layer. The packaging foil has at least one weakening zone in which the tear-inhibiting properties of the packaging foil are reduced by a plurality of perforations that are present in the first layer. The density of perforations in the weakening zone lies between 50 and 250, preferably between 50 and 150 and particularly preferred between 70 and 130 perforations per cm.sup.2.
