A laminate tube with an invisible longitudinal overlapped side seam formed from overlap welding an edge of one margin of a laminate sheet comprising an outer plastic layer (A), a barrier layer (B), and an inner plastic layer (C) of the same material type as the outer plastic layer (A) to the other edge of the opposite margin of the laminate sheet, such that an inner surface of the laminate tube has a hump in a overlapped region, while an outer surface of the laminate tube is smooth without a hump in the overlapped region; and a process for manufacturing the laminate tube by a laminate tube manufacturing machine. The laminate permits fracture-proof welding of longitudinal margins of said laminate to give a continuous tube which is suitable for manufacturing of high-quality plastic tubes, high-quality plastic bags and the like.

A laminated pre-applied membrane is provided. The membrane comprises a layer of polyethylene and a rubber or rubber-based layer.

A film for laminating glass includes a first surface layer, a second surface layer opposite the first surface layer, and an interlayer disposed between the first surface layer and the second surface layer, wherein the interlayer includes a trioxane-based compound.

A method for producing a half-shell that includes an insert member for a high-pressure vessel using a mould having a first mould section forming a female mould. The method includes laying a pre-heated first plastic sheet on the first mould section; pressing or adhering, via one or more of a partial vacuum or a pressure, the first plastic sheet onto the first mould section; positioning the plastic of the first plastic sheet in areas behind a back-taper of the insert member at a lateral distance from the insert member, or positioning the insert member, after the pressing or adhering, so that plastic of the first plastic sheet is disposed in areas behind a back-taper of the insert member at a lateral distance from the insert member; and pressing or adhering, via a slide, partial vacuum, or pressure, the plastic of the first plastic sheet behind the back-taper and laterally distanced from the insert member, onto the insert member so that a space behind the back-taper of the insert member is filled with the plastic.

A multilayer film is provided. The film includes a first inert layer, a first tie layer, a nail sealable layer, a second tie layer, and a second inert layer. Where, the nail sealable layer is between the first tie layer and the second tie layer, the first tie layer is between the first inert layer and the nail sealable layer, the second tie layer is between the second inert layer and the nail sealable layer, the total film thickness is between 0.002 inch and 0.010 inch, and the film has a Water Vapor Transmission Rate of less than 0.5 grams per one hundred square inches per day.

This invention relates to an anisotropic multilayer film and the process of making a multilayer film, wherein a supercritical blowing agent is introduced to at least one layer, wherein at least one layer comprises 10 to 100 percent by weight LLDPE with a melt index of 0.2 to 2 g/10 min. The film in this invention can have a surface with an average Sheffield smoothness, according to TAPPI T 538, of less than 100. The film in this invention can have a puncture propagation tear resistance, in accordance with ASTM D2582, greater than 500 g/mil.

A floor plank having a rigid, composite core having an upper side and a underside, the core being thermally stable and formed of PVC and calcium carbonate material that does not include ortho-phthalates, a wood veneer having a lower surface on the upper side of the core and further including an exposed surface, a protective coating on the exposed surface of the wood veneer, the protective coating formed of catalyzed polyurethane having aluminum oxide particles, and a thermo-acoustic cushion coating on the back surface of the core. A method of making is also provided.

A solar cell module is provided. The solar cell module includes a first substrate, a second substrate opposite the first substrate, a cell unit disposed between the first and second substrates, a first thermosetting resin layer disposed between the cell unit and the first substrate, a first thermoplastic resin layer disposed between the cell unit and the first thermosetting resin layer, a second thermosetting resin layer disposed between the cell unit and the second substrate, and a second thermoplastic resin layer disposed between the cell unit and the second thermosetting resin layer.

The present invention relates to cross-linked vacuum skin packaging (VSP) films used as top webs for VSP packages endowed with easy opening features and to VSP packages obtained therefrom. The films of the invention comprise at least one layer of a frangible blend of incompatible polymers. The easy-to-open VSP packages obtained therefrom may advantageously include very simple and cheap supports.

A production method for a waterproof and wear-resistant composite floor, comprising: first manufacturing a PVC composite layer preform (3); then performing a corona treatment and a punching treatment on a soft cushion layer (2); and finally, compounding, at one time, the PVC composite layer preform (3), the soft cushion layer (2) and a waterproof substrate layer (1) into one. Said process is simple and easy to implement, shortening the production cycle, reducing the manpower and material resources required by the production process and reducing the production cost; moreover, the waterproof and wear-resistant composite floor produced has a simple structure, and also has very good waterproof and wear-resistant performance; in addition, the waterproof and wear-resistant composite floor will not swell, and will also not split into layers or deform easily.
