HEAT-SHRINKABLE LABEL, PACKAGE, AND MANUFACTURING METHOD FOR HEAT-SHRINKABLE LABEL
Provided are a heat-shrinkable label and a package each having solvent bonded-portion where solvent penetration-through is not caused even when the film is thin. Provided are particularly a heat-shrinkable label and a package each having solvent bonded-portion gaining a high peel strength stability even when the film is passed through a tubing step made high in speed. A heat-shrinkable label has a tubular shape, in which both end portions of a heat-shrinkable polyvinyl chloride-based film or a heat-shrinkable polystyrene-based film are bonded to each other with a solvent composition. The solvent composition contains at least one organic solvent selected from the group consisting of tetrahydrofuran (THF), methyl ethyl ketone (MEK) and ethyl acetate, and at least one resin selected from the group consisting of polyester, polypropylene and hydrogenated petroleum resin, and the end portion bonded has a peel strength of 2 N/15 mm or more.
HEAT-SHRINKABLE POLYESTER-BASED LABEL, PACKAGE, AND METHOD FOR PRODUCING HEAT-SHRINKABLE POLYESTER-BASED LABEL
Provided are a heat-shrinkable polyester-based label, and a package which each have a solvent-bonded portion where no solvent permeation-through is caused even when a film of the label is small in thickness. Provided are, in particular, a heat-shrinkable polyester-based label and a package which each have a solvent-bonded portion giving a high peel strength stably even through a high-speed tubing step, or even when the film is a heat-shrinkable polyester-based film in which a PET-bottle-recycled material is used in a large proportion. The label is a heat-shrinkable polyester-based label that is a tubular label in which both end portions of a heat-shrinkable polyester-based film are bonded to each other with a solvent composition. In this label, the solvent composition is a solvent composition containing at least 1,3-dioxolane and/or tetrahydrofuran (THF), and a polyester, and the end portion bonded has a peel strength of 2 N/15 mm or more.
MDO THERMORESISTANT HEAT-SHRINKABLE FILM
The present invention relates to an MDO heat-shrinkable film of a copolymer polyester having excellent thermal resistance. In particular, the present invention provides a copolymer polyester MDO (machine direction orientation) thermoresistant heat-shrinkable film that consists of a copolymer polyester resin including isosorbide and 1,4-cyclohexanedimethanol at an optimized content ratio as a diol component copolymerized with an acid component including terephthalic acid, and having a number average molecular weight of 18,000 g/mol or more, and can be used for labels, cap seals, direct packaging, etc. of various containers due to the high shrink initiation temperature.
METALLIZED, ORIENTED, AND THIN LLDPE FILMS
This disclosure provides compositions and methods for an oriented film that may include a core layer consisting essentially of biaxially oriented linear low-density polyethylene, wherein the core layer has a first side and a second side. Further, the film may include a first sealant layer consisting essentially of biaxially oriented linear low-density polyethylene on the first side, and a second sealant layer consisting essentially of biaxially oriented linear low-density polyethylene on the first side, wherein the linear low-density polyethylenes in each of the film's layers may be of more than one type/grade, have the same or different densities, or both. Further still, the film is 30 m or less in thickness, has a water-vapor transmission rate of 1 g/m.sup.2/d at 38 C. and 90% relative humidity, and has an oxygen transmission rate of 100 cm.sup.3/m.sup.2/d at 23 C. and 0% relative humidity.
Multilayer film for label and a method for providing such
The invention relates to providing a method for obtaining a multilayer film for thermally inducible shrink labels, products thereof and use of such products.
IRIDESCENT BADGES FOR VEHICLES
An iridescent vehicle badge (and methods for making it) that includes a translucent, polymeric badge having a non-planar shape and comprising an interior and an exterior surface. Further, at least one of the surfaces of the badge comprises a plurality of diffraction gratings that are integral with the badge, each having a thickness from 250 nm to 1000 nm and a varying period from 50 nm to 5 microns. In some cases, the thickness can range from 500 nm to 750 nm. The period, in some cases, can vary within a set of discrete values in one or more portions of the at least one of the surfaces of the badge, e.g., from 150 nm to 400 nm.
Full Body Decoration of Blow Molded Tubes
A process for producing a tube, comprising forming a blow-molded article and removing a bottom portion of said blow-molded article. The blow-molded article includes (i) a head portion, and (ii) a tube portion integral with said head portion. The tube may be decorated, such as with a label.
RECYCLED POLYSTYRENE PLASTIC FILM, ACOUSTO-MAGNETIC ANTI-THEFT LABEL, ACOUSTO-MAGNETIC ANTI-THEFT LABEL HOUSING, AND PREPARATION METHODS THEREOF
Disclosed is a recycled polystyrene (PS) plastic film prepared from 100% of a waste PS plastic or prepared from a waste PS plastic and a modification material, where a content of the waste PS plastic is greater than or equal to 1% and less than 100% and a content of the modification material is greater than 0% and less than or equal to 99%. The preparation of the recycled PS plastic film with the waste PS plastic can save resources. In addition, the waste PS plastic is modified by the modification material to improve the performance of the plastic, which is conducive to preparation of an acousto-magnetic (AM) anti-theft label housing with excellent performance. Also disclosed are a preparation method of the recycled PS plastic film, an AM anti-theft label housing made of the recycled PS plastic film and a preparation method thereof, and a corresponding AM anti-theft label.
MDO thermoresistant heat-shrinkable multilayer film
The present invention relates to an MDO thermoresistant heat-shrinkable multilayer film of a copolymer polyester having excellent thermal resistance. In particular, the present invention provides an MDO thermoresistant heat-shrinkable multilayer film that includes multiple skin layers capable of improving thermal resistance formed on a substrate layer capable of providing high shrinkage, and simultaneously has excellent thermal resistance and high shrinkage properties through MD orientation instead of the conventional TD orientation method.
Void-containing heat-shrinkable polyester film
The present invention provides a void-containing heat-shrinkable polyester film which has satisfactory shrinkage finishing properties and printability even if productivity is improved. The void-containing heat-shrinkable polyester film is a multilayer structure having a non-foamed layer on both outer sides of the foamed layer, and by controlling the film thickness, density, and number of moles of the amorphous component on both outer sides, specific heat shrinkage characteristics and gloss can be improved.
