Heat-shrinkable multilayer film and heat-shrinkable label
The present invention provides a heat shrinkable multilayer film which has excellent adhesiveness between front and back layers and an interlayer not only at normal temperature but also at low temperature to effectively prevent delamination and is less likely to have residual white streaks along creases. The present invention also provides a heat shrinkable label including the heat shrinkable multilayer film. The present invention relates to a heat shrinkable multilayer film including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, the front and back layers and the interlayer being stacked with the adhesive layers interposed therebetween, the adhesive layers each containing 20 to 65% by weight of a polystyrene resin and 35 to 80% by weight of a polyester elastomer.
Thermoplastic polymer composition and molded article
The present invention is a thermoplastic polymer composition which contains 10-120 parts by mass of a polar group-containing polypropylene resin (B) per 100 parts by mass of a thermoplastic elastomer (A) that is a block copolymer having a polymer block containing an aromatic vinyl compound unit and a polymer block composed of a conjugated diene unit having 40% by mole or more of 1,2-bonds and 3,4-bonds in total, or a hydrogenated product of the block copolymer (provided that a thermoplastic polymer composition containing 1 part by mass or more of a polyvinyl acetal resin is excluded). This thermoplastic polymer composition is able to be bonded with a ceramic, a metal or a synthetic resin without requiring a primer treatment, and has excellent flexibility, mechanical characteristics, moldability, heat resistance and storage stability.

RECYCLABLE SURFACE COVERING AND METHOD AND SYSTEM FOR MANUFACTURING A RECYCLABLE SURFACE COVERING
A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.
Refresh agent
A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C9-C15 aliphatics, C9-C15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.
COATING COMPOSITION FOR SKIN-CONTACTING SURFACE OF ELASTOMERIC ARTICLES AND ARTICLES CONTAINING THE SAME
The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently hydrates when contacted with a moisturized skin surface to convert into a liquid lotion form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.
SUSTAINABLE INJECTION MOLDED ARTICLES
A sustainable thermoplastic composition made by forming a mixture of virgin polypropylene and post-industrial-recycled material (PIR). The PIR may include a thermoplastic, elastomeric-polymer and a spunbond component. The mixture is melt-blended in an extruder. Extruded materials made from the mixture demonstrate little variance in the results of the IZOD Impact Test of materials containing 30 to 70 percent PIR, and a material containing 100 percent virgin polypropylene. In addition, the extruded materials containing 30 to 70 percent PIR demonstrate a substantially constant strain at yield, that strain at yield being substantially equal to that demonstrated by a material containing 100 percent virgin polypropylene.
Resin blend for melting process
Provided are a resin blend for forming a layer-separated structure, a pellet, a method of preparing a resin article using the same and a resin article. The resin blend may include a first resin, and a second resin that comprises a resin to which at least one organic functional group selected from the group consisting of an alkyl group having 2 to 20 carbon atoms, an alicyclic group having 5 to 40 carbon atoms and an aromatic group having 6 to 40 carbon atoms is introduced, that has a difference in melt viscosity from the first resin of 0.1 to 3000 pa*s at a shear rate of 100 to 1000 s.sup.1 and a processing temperature of the resin blend, and that has a difference in glass transition temperature from the first resin of 10 C. to 150 C. The resin blend can improve mechanical and surface characteristics of a resin article.
