Provided is a method for producing a packing sheet with improved insulation and storage properties, which can greatly reduce logistics costs by minimizing a volume during storage and transportation and also greatly increase insulation.

A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (12, 2), capturing a portion of the parison (12, 2) within a mold (15), and inflating the captured portion of the parison (12, 2) against the mold (15). The captured portion of the parison (12, 2) is inflated against the mold (15) by introducing the liquid product into an interior of the captured portion of the parison (12, 2), wherein the liquid product forms an end product to be sealed within the resultant container.

A bellows includes: an at least two-layer construction including at least a first layer and at least a second layer. In an embodiment, the layers are inseparably interconnected due to a manufacturing process of the layers. In an embodiment, the layers comprise different materials and/or have different densities. In an embodiment, at least one of the layers comprises a TPE material.

It is an object of the present invention to provide a foam molding resin containing LDPE capable of enhancing foaming magnification. According to the present invention, there is provided a foam molding resin containing low-density polyethylene, wherein the low-density polyethylene has a melt tension of 100 to 250 mN and a shear viscosity of 350 to 450 Pa.Math.s.

Disclosed is a process for producing a multimodal ethylene polymer composition suitable for producing films by blow moulding. The process comprises (i) copolymerising ethylene and an alpha-olefin comonomer in a first polymerisation step to produce a first ethylene copolymer (PE1); (ii) copolymerising ethylene and an alpha-olefin comonomer in a second polymerisation step in the presence of the first ethylene copolymer to produce a first ethylene polymer mixture (PEM1), wherein the MFR.sub.2 of PE1 is higher than the MFR.sub.2 of PEM1; and (iii) copolymerising ethylene and an alpha-olefin comonomer in a third polymerisation step in the presence of the PEM1 to produce a second ethylene polymer mixture (PEM2) having a density of from 915 to 925 kg/m.sup.3 and a melt flow rate MFR.sub.5 of from 0.3 to 5 g/10 min.

According to the present invention, provided is a foam molding resin containing low-density polyethylene, wherein a strain hardening degree of the low-density polyethylene is equal to or more than 0.40.

A method of forming a balloon for a medical device is provided including extruding a cylindrical tube of silicone material, partially curing the cylindrical tube, inflating the cylindrical tube, and fully curing the balloon. The cylindrical tube is partially cured by exposing the cylindrical tube to a first ultraviolet light source. The cylindrical tube is inflated within a mold to form the balloon. The balloon is fully cured by exposing the balloon to a second ultraviolet light source.
