A semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. The semi-crystalline blended polymer displays a DSC melt peak enthalpy of at least about 3 joules/g. The semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. The semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.

A multi-shot moulding part structure includes a first structural part, an ink decoration layer, and a second structural part. The first structural part has a first area surface, a second area surface, and a joining surface located on the second area surface. The joining surface is non-parallel to the second area surface. The ink decoration layer is spread on the first area surface and the second area surface, but not on the joining surface. The second structural part is combined with the first structural part and covers the second area surface. The second structural part touches the joining surface. By the second structural part touching the joining surface of the first structural part that is not coated with the ink decoration layer, the structural bonding strength between the first structural part and the second structural part is enhanced.

A laminated metal sheet for a metal container lid includes a polyester resin layer formed on a metal sheet. The polyester resin layer is composed of an A and a B layer, wherein the melting point of the A layer is lower than the melting point of the B layer by 20° C. or more, the A layer includes a molten layer where the value of the ratio of a peak intensity I.sub.0° to a peak intensity I.sub.90° is 1.5 or less, the B layer includes an orientation layer where the value of the ratio of the peak intensity I.sub.0° to the peak intensity I.sub.90° is 3.0 or more, the thickness of the A layer is within the range from 5 μm or more to less than 30 μm, and the thickness of the B layer is within the range from 0.5 μm or more to less than 6.0 μm.

A method of making laminate foam material is provided. The laminate foam material includes a layer of non-foam material sandwiched between two layers of foam material. The non-foam material is bonded to the foam material, such as with a bonding agent and/or by heating respective surfaces of the foam material until the surface softens or melts. When a heating process is utilized, the non-foam material is pressed against the softened or melted foam material. As the foam material begins to cool, the non-foam material becomes bonded to the foam material. The non-foam material is narrower than the foam material and is positioned relative to the foam material such that the edges of the non-foam material are concealed by the foam material. Foam products, such as foam mats, can be formed from the laminate foam material by cutting across the width of the foam material.
