Graft compositions, useful for tie-layer adhesives, are disclosed. The graft compositions comprise the reaction product of a live, grafted polyolefin and an olefin elastomer. The grafted polyolefin is first made by heating a polyolefin and an unsaturated monomer. Further reaction of the live, grafted polyolefin with an olefin elastomer provides the graft composition. Grafting efficiency is boosted dramatically by the presence of the olefin elastomer and use of the additional reaction step. The graft composition, when formulated into a tie-layer adhesive at low concentration, affords multilayer structures with good adhesion and high clarity.

A crosslaminate is formed from two oriented plies of thermoplastic polymer material, arranged so that their orientation directions cross one another, the plies being heat sealed together. Each ply is semi-fibrillated, that is consist of linear thin regions of biaxially oriented material and thicker linear bosses between the thinner regions. The webs are sealed primarily through bonds formed at the intersection of the bosses (thicker regions). The array of bosses has a division less than 2 mm. The laminate has improved aesthetic and strength properties. A method for forming the crosslaminate involves segmental stretching of the material to form the thinner regions, and apparatus comprising intermeshing grooved stretching rollers having sharp-edged crests is described.

Thermal expansion control employing platelet fillers

Bilayer platelet fillers are employed to compensate for a positive coefficient of thermal expansion (CTE) of an embedding polymeric material, or even to provide a composite structure having a negative CTE to eliminate or alleviate thermomechanical stress and/or delamination during thermal cycling. A bilayer platelet includes two joined layers having different CTEs. The CTE mismatch induces bending of the bilayer platelets, thereby causing cavities at temperatures lower than the joining temperature at which the bilayers are joined. The decrease in the volume of the polymeric material and the bilayer platelets at low temperatures is compensated by an accompanying increase in the volume of the cavities so that the composite structure has a temperature independent volume, a low net CTE, or even a negative CTE.

A structured-core laminate panel can be made in an efficient, structurally sound manner without the use of adhesives (film or liquid forms) using materials with different melt or glass transition temperatures. In one implementation, a manufacturer positions one or more resin substrates about a structured core, which comprises a relatively high melt or glass transition temperature compared with that of the one or more resin substrates. The manufacturer heats the assembly to at least the glass transition temperature of the resin substrates, but not to the melt or glass transition temperature of the structured core. This allows the one or more resin substrates to melt and bond (mechanically, chemically, or both) to the structured core on one side (or inner surface), while maintaining a substantially planar or original conformation on an opposing side (or outer surface).

The present invention relates to film structure suitable for use in stand up pouches comprising all polyethylene material. The film structure can be a monolayer film or a multilayer film structure having specific requirements for each layer. The combination results in a film structure having adequate stiffness to function as a stand-up pouch while also providing acceptable water vapor transmission rates and good tear resistance. Such films have improved sustainability characteristics as they should permit down-gauging of the films and, can more easily be recycled, at least for the preferred embodiment comprising only polyethylene resins. 1. A laminated film structure suitable for use in stand up pouches comprising: [{'sup': '3', 'i) at least one surface layer (A) comprising from 70 to 100 percent by weight of the layer (A) of a linear low density polyethylene having a density from 0.89 to 0.91 g/cmand a melt index of less than 1.3 dg/min, and a peak melting point in the range of from 85° C. to 100° C., and a molecular weight distribution, Mw/Mn, in the range of from 2.0 to 3.0; and'}, {'sub': 3', '10, 'sup': '3', 'ii) at least one additional layer (B) comprising from 70 to 100 percent by weight of the layer (B) of a first multimodal polyethylene polymer having a multimodal distribution in terms of molecular weight, wherein said first multimodal polyethylene comprises units derived from ethylene and at least one C-Calpha-olefin, and wherein the first multimodal polyethylene polymer has a density in the range of from 0.950 to 0.965 g/cm, a melt index in the range of from 0.8 to 1.2 dg/min, a peak melting point in the range of from 120° C. to 135° C. as measured by a differential scanning calorimeter, and a molecular weight distribution, Mw/Mn ratio greater than 5.0;'}], 'a) a first film comprising [{'sub': 3', '10, 'sup': '3', 'i) a first surface layer (C) comprising from 60 to 100 percent by weight of the layer (C) of a second multimodal polyethylene polymer having a ...

A mold assembly for forming a component exhibiting a sealed interior, including providing first and second mold halves, forming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed. 1. A mold assembly for forming a component exhibiting a sealed interior , said mold assembly comprising:a stationary supported mold half;a rotary platen supported mold half, each of said mold halves being movable in directions towards and away from one another in order to define each of engaged/closed and opened/separated positions;each of said mold halves exhibiting a plurality of shell forming locations defined in opposing configured surfaces thereof for forming a first half shell of material in said stationary supported mold half and a second half shell of material in said rotary platen supported mold half and, upon mating said mold halves together in a first closed mold configuration; andupon separating the mold halves and subsequently rotating the rotary platen supported mold half 180° in order to reposition the second half shell relative to a further shell forming location associated with the first mold half, the first and second half shells are arrayed in opposing fashion with a perimeter extending and formed edge of each half shell arranged in contact with one another;said mold halves being subsequently reclosed prior to a ...
