The invention provides a process of obtaining a bi-oriented co-extruded film of 7 layers by triple bubble process for autoclave sterilization processes, which unlike the current existing materials for food sterilization, the invention does not require an individual manufacturing process of each sheet and subsequent lamination, but it is manufactured in a single step, in addition no metal compound is included in its composition, and provides a shelf life of more than a year in food products that are packaged in the process of sterilization (retort) inside the film.

A manufacturing method including a first conveying step of conveying the sheet in a lateral or oblique lateral direction along a sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the sheet on the sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the sheet and the film raw material after the tip part overlaps the sheet on the sheet pass line, the second conveying step conveying the sheet and the film raw material in a mutually overlapping state along the sheet pass line; and an introducing step of introducing the sheet and the film raw material in the mutually overlapping state to the joining part from the sheet pass line.

The invention comprises a peelable membrane for resealably closing a metal end comprising an outer layer, a tacky layer, and a heat seal layer. The heat seal layer is permanently sealed to the metal end to cover at least one opening in the metal end. The tacky layer causes the peelable membrane to be resealable onto the metal end.

Provided are a printing sheet having a coating layer for receiving ink on at least one surface of a substrate and having excellent printability, excellent adhesiveness between the substrate and the coating layer, and excellent antistatic performance and thus being less likely to cause troubles such as paper jams during printing, and further having excellent properties such as water resistance and weather resistance in a printing sheet; and a method for producing the same. The printing sheet includes a coating layer formed by blending (meth)acrylic ester-based resin particles in a proportion of 1% by mass or more and 10% by mass or less and clay in a proportion of 50% by mass or more and 70% by mass or less in a continuous phase made of an acrylic polymer.

The use of titanium dioxide particles coated by an organic coating for increasing the hydrolysis resistance of an oriented polyester film, particularly wherein the organic coating does not comprise or is not derived from a silane, and particularly wherein the organic coating is selected from an organophosphorus compound and a polymeric organic coating; and oriented polyester films comprising such titanium dioxide particles coated by an organic coating; and photovoltaic cells comprising such films.

The continuity of a functional layer of a web (32, 60, 78) is assessed by forwarding the web, detecting (42, 63) the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component (360) in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component (360) in the functional layer. The detectable component (360) can be active or passive. Also included are systems for carrying out the process.

The present invention discloses a hydrophobic automobile rubber seal strip flocking belt and a preparation method thereof, wherein the flocking belt comprises a flocking belt film, flocking belt glue, villi and flocking paint; the flocking glue is roller-coated or sprayed on the flocking film to form a flocking glue layer; and the villi is implanted on the flocking glue layer by high voltage static electricity in electrostatic chamber. The flocking coating is roller-coated or sprayed on the villi to form a flocking coating which comprises fluorosilicone modified waterborne polyurethane resin, polyurethane modified acrylic emulsion, organic molybdenum, organic silicon, curing agent and solvent. Accordingly, the preparation method includes such steps as film forming, glue applying, electrostatic flocking, flocking curing, spraying or roller-coating, and coating curing, etc. The flocking belt described in the present invention is installed in a guide groove of the automobile glass, which is enabled to solve the problem of abnormal noise caused by rising and falling of glass of automobile windows. In addition, the flocking coating feels soft and smooth.

Systems and methods for forming pellets from mixed plastic materials are disclosed. An example method may include a method for forming pellets from mixed plastic materials without needing to screen or filter the mixed plastic materials. The method may include disposing a mixed plastic material into an extrusion apparatus, advancing the mixed plastic material through a die to form strands, and cutting the strands into a plurality of pellets.

An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.

An extruder for multi-lumen tubular products with multi-coronal arrangement comprises a main body (2) defining a passage cavity (2a) and an average outflow direction (2b), as well as an input surface (3) and an exit surface (4) respectively formed on opposite faces of the main body (2) and defining respective entry areas afferent to and efferent from the passage cavity (2a); the extruder further comprises an expansion portion (4a) associated with the exit surface (4) and adapted to mutually orient spontaneous expansive flows of said extrusion material through the exit surface (4) in reciprocal directions of mutual intersection.
