A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.

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 present invention relates to a biodegradable sheet comprising at least two polymer layers, wherein a first polymer layer comprises a mixture of at least two different biodegradable polymers selected from the group consisting of PLA, PCL, PBS and PBSA; and wherein a second polymer layer comprises a biodegradable polymer selected from the group consisting of PBS, PBSA, a mixture of PLA and PBS, and a mixture of PLA and PBSA.

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.

The adhesive tape includes: a resin layer that is formed by applying resin coating, the resin coating containing a resin having an acid number of 50 mg/g or more and 130 mg/g or less, and at least one type of cross-linking agent selected from between an epoxy-based cross-linking agent and a metal chelate cross-linking agent; and an adhesive layer that is laminated on or above the resin layer, and is formed by applying adhesive coating, the adhesive coating containing a resin including a hydroxyl group, and a metal chelate compound.

A waterproof membrane is described that includes a barrier layer and a functional layer. The functional layer can include a thermoplastic polymer that changes consistency under the influence of highly alkaline media, and an adhesive. The production and use of the membrane are also described. The functional layer of the membrane can be designed in the form of a film, a coating, or a nonwoven fabric. The fibers in the fabric can include a hard core that is surrounded by a polymer layer, is inert prior to coming into contact with liquid concrete and acts as a protective layer. Thus, the membrane is protected from premature aging and allows work to be performed with the seal in place. During the concreting process, i.e. when the functional layer comes into contact with liquid concrete, the polymer dissolves and thus allows the adhesive to bond to the concrete. The functional layer thus acts as an adhesive sealing compound and the seal is leakproof.

To provide a layered polyester film having excellent mechanical properties, transparency, heat resistance, and gas barrier property. A layered polyester film including a polyester film and a thin film layer, wherein the polyester film is a biaxially oriented polyester film including a dicarboxylic acid component containing mainly a furandicarboxylic acid and a glycol component containing mainly ethylene glycol, the covering layer is formed on at least one surface of the polyester film, and the layered polyester film has a plane orientation coefficient P of not less than 0.005 and not more than 0.200, and a thickness of the layered polyester film is not thinner than 1 m and not thicker than 300 m.

There is disclosed an in-mould labelling process for the manufacture of a labelled article comprising the steps of: feeding a labelstock web into a mould; forming an article in the mould such that the formed article contacts and effectively adheres to a label of the labelstock web; detaching the adhered label from the labelstock web; and removing the formed and labelled article from the mould.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
