A press-through foil (2) for press-through packaging (1) is formed from a plastic mixture made up of such plastics that, in the melt and in the foil formed therefrom, they form at least two phases, that is non-homogeneities, so that the tensile strength and impact resistance are reduced. A packaged product can be appropriately easily pressed through this foil, but is completely sealed prior to that. |

An open-cell foam of a cross-linked polyolefin possessing uniform physical properties, a high degree of expansion, and a high open-cell ratio can be produced with high operational efficiency and high material utilization by a method which includes thermally shaping under pressure a foamable and cross-linkable polyolefin composition capable of being heated with a microwave, then heating the composition by irradiation with a microwave thereby inducing partial decomposition of a cross-linking agent and a foaming agent contained in the composition, subsequently externally heating under normal pressure the resultant intermediate partially foamed product thereby effecting decomposition of the remainders of the cross-linking agent and foaming agent, and thereafter subjecting the resultant foam to mechanical deformation thereby establishing intercommunication among the cells. The surface of the foamable and cross-linkable polyolefin composition may be heated prior to the heating with a microwave to effect partial cross-linking of the surface part of the composition. |

A glass fiber-reinforced composite material is produced by treating glass fibers with a silane composition comprising silane molecules having amine functional groups and silane molecules having ethylenically-unsaturated functional groups; admixing the treated glass fibers with a polyolefin resin, and a fiber bonding agent comprising a polymerizable unsaturated organic compound having at least two polymerizable unsaturation groups, a vinyl-polymerizable unsaturated, hydrolyzable silane, and a free radical generator, and exposing the resultant mixture to conditions of temperature and pressure sufficient to cause the formation of a glass fiber-reinforced composite material. The use of the silane composition promotes improved impact strength of the composite. |

A method for foaming heat foamable thermoplastic resin preforms and the product produced thereby. Said preforms are foamed in a series of foaming stages, said series comprising at least one stress-relieving foaming stage and at least one additional foaming stage subsequent thereto and at a higher temperature. This method facilitates the production of foam sheets, slabs and planks of better quality than that provided by previously known single stage foaming methods. In an example, a crosslinked, expandable, polyethylene preform is foamed by such a method using two foaming stages. |

A process for the preparation of a product expandable to form a foamed plastic comprises mixing a polymer of ethylene or propylene with at least 10% by weight based on the polymer of a finely-divided inorganic solid, and contacting in the solid state with a liquid organic blowing agent. The finely divided inorganic solid may be: "Aerosil" (Registered Trade Mark), SiO2, per lite, kaolin, asbestos powder, silicates, chalk or MgO. The liquid organic blowing agent may be a hydrocarbon, halogenated alkane, methanol, acetone and low-boiling esters. Wax having a melting-point at least 10 DEG C. higher than the polymer may be present in the mixture. In a typical Example (1) high pressure polyethylene, MgO and wax were mixed at 115 DEG C. and the mixture immersed in n-pentane, separated from the liquid and the mixture extruded at 80-110 DEG C. to produce a fine cellular product. |
