A laminated polypropylene-based film suitable for use as a lidding film having an exterior film, a barrier layer, and a sealing layer. The lidding film has a total composition including high levels of polyolefin-based polymers and polypropylene-based polymers such that the material can be processed efficiently in a polypropylene recycling process. Advantageously, the film retains the properties required to suitably withstand sterilization and pasteurization processes and produce a high-quality packaged product.

A method of microcellular foam molding an article includes feeding plastic granules to a hopper; supplying a supercritical fluid (SCF) to the hopper to effuse through the plastic granules; conveying the effused plastic granules to a buffer tank; and conveying the effused plastic granules in the buffer tank to a mold of an injection molding machine to perform foam molding on the effused plastic granules to produce a foamed article. In a second embodiment, the injection molding machine is replaced by an extrusion press.

The present invention is a manufacturing method for obtaining a molded article having foam layer inside for providing a foaming agent, a device, a mold, a molding machine, a means for increasing the foaming ratio and a means for increasing coating appropriateness used for manufacturing resin having foaming properties. When the resin having compatibility (miscibility) with the resin to be blended is used as a carrier resin used for manufacturing a masterbatch of the foaming agent, the molded article having an excellent outer appearance can be obtained. When the sodium bicarbonate which is an inorganic foaming agent is used for the foaming agent, a sodium carbonate, which is a foam residue remaining in the molded article after the foaming agent is decomposed to generate the foaming gas, reduces the adherability of the coating film. Thus, when the acid cleaning is preliminarily performed to remove the sodium carbonate, the coating appropriateness is satisfied. When performing the GCP, the thickness of the skin layer located at the surface varies depending on the surface temperature of the mold. In general, the means using the heated steam is generally used for increasing the temperature of the mold. In the present invention, the means for heating the magnetic fluid (liquid) by high frequency induction heating is used. Thus, the temperature of the mold can be safely increased at low cost with heating efficiency. When a mold-back or a core-back is performed for obtaining the molded article having high foaming ratio, the resin is separated from the fixed side. The present invention provides the means for solving the above described problem of the separation by using the gas.
