POLYPROPYLENE FILM WITH INCREASED HYDROPHOBICITY
The present invention relates to a multi-layer polypropylene film comprising: A base layer of polypropylene (2); Optionally, a tie layer (3) comprising a blend of polypropylene and an sacrificial engineering thermoplastic; A top layer (1) comprising film having a structured surface with water contact angles (WCA) superior to 104.5°, preferentially superior to 110°, more preferentially uperior to 120°, more preferentially superior to 130°; Wherein the top layer comprises a blend 20 to 40 wt % of polypropylene and 60 to 80 wt % of said engineering thermoplastic and in which the engineering thermoplastic has been selectively etched in order to create the said structured surface.
Adhesive sheet
In an embodiment, an adhesive sheet has an expandable adhesive layer 2 on one side or both sides of a base 1, wherein the expandable adhesive layer 2 contains an epoxy resin including a polyfunctional epoxy resin, a phenol resin as a curing agent, an imidazole-based compound as a curing catalyst, and a temperature-sensitive foaming agent. The adhesive sheet has properties in good balance, such as fast curability, heat resistance, and adhesiveness, and also excellent properties such as thermal conductivity attributed to a good filling property.

Intermediate transfer medium, combination of intermediate transfer medium and thermal transfer sheet, and method for forming print
An intermediate transfer medium that allows formation of high-density images on a transfer layer while suppressing printing unevenness and provides good foil cutting properties of the transfer layer, a combination of the intermediate transfer medium and a thermal transfer sheet, and a method for forming a print using the intermediate transfer medium. In an intermediate transfer medium having a transfer layer on a substrate, the transfer layer has a single layer structure including only a receiving layer or a layered structure including the receiving layer. When the transfer layer has the layered structure, the receiving layer is located furthest from the substrate among layers constituting the transfer layer. The receiving layer contains a binder resin having a number average molecular weight of 8000-32000 and a release agent. The content of the release agent based on the total mass of the receiving layer is 6% by mass or more.
Container and method for manufacturing container
There is provided a container that makes it possible to suppress intrusion of bacteria from the tip of a pleat part into the inside of the container. The container includes: a main body that includes a body part defining a containing portion and a flange part extending outward from an upper portion of the body part; and a lid that is joined to the flange part of the main body via an outer edge seal portion so as to cover the containing portion, the lid being formed by a lid member folded back at a fold-back portion such that portions of the lid member overlap each other. The lid has: a pleat part that includes the portions of the lid member overlapping each other and that extends from an edge of one side to an edge of the other side of the lid in a first direction; and a first lid part and a second lid part that are formed by the lid member and that are arranged on opposite sides of the pleat part. The pleat part includes: a pleat seal portion in which inner surfaces of the portions of the lid member are joined together and that extends from the edge of the one side to the edge of the other side of the lid in the first direction; and a steam passing portion that includes a through hole or a cutout formed in the pleat seal portion. Seal strength of the pleat seal portion is lower than that of the outer edge seal portion.
Paper label with polymer film reinforcement and method of manufacture
A method for manufacturing a roll of stock material for making a label having a shelf portion with pressure sensitive adhesive and a bib portion with deadened adhesive is provided. The shelf portion includes a layer of polymer. A continuous layer of paper is bonded to a continuous layer of polymer with applied strips of catalyzed adhesive from a roller. Unbonded strips of polymer are kiss-cut and removed to expose the paper between bonded strips of polymer. A continuous layer of pressure sensitive adhesive is applied over the polymer and exposed paper. Strips of deadening agent are applied over the layer of pressure sensitive adhesive that overlays the exposed paper. The pressure sensitive adhesive and deadening agent are cured and a release layer is applied over them.
ADHESIVE SHEET AND POLISHING PAD WITH ADHESIVE SHEET
The present invention aims to provide an adhesive sheet excellent in both shear strength and slurry resistance at high temperature and excellent in removability that enables removal without adhesive residue. The present invention also aims to provide a polishing pad with an adhesive sheet including the adhesive sheet. Provided is an adhesive sheet including at least one adhesive layer, the adhesive layer containing a base polymer, a tackifier resin (T1) having a hydroxy value of less than 20 mgKOH/g, and a tackifier resin (T2) having a hydroxy value of 20 mgKOH/g or more and 120 mgKOH/g or less, the base polymer being a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound, and the adhesive layer containing the tackifier resin (T1) in an amount of 10 parts by weight or more and 60 parts by weight or less relative to 100 parts by weight of the base polymer, and the tackifier resin (T2) in an amount of 1 part by weight or more and 40 parts by weight or less relative to 100 parts by weight of the base polymer.
PRESSURE-SENSITIVE ADHESIVE SHEET
To provide a PSA sheet having excellent IR-blocking properties. Provided is a PSA sheet having a substrate layer as well as a PSA layer placed on one face of the substrate layer. The PSA sheet has 5% or lower light transmittance in the thickness direction in a wavelength region of 780 nm to 2500 nm.
Easy access woven plastic bags
A woven laminated plastic bag having a weakened portion is provided. The weakened portion is generally defined by a plurality of perforations in the bag. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.
