TRILAMINATE PROCESS TO PRODUCE A VARIABLE DENSITY POLYMER MULTILAMINATE, USING A FORMULATED POLYMERIC ADHESIVE
A process for making a multilaminate containing polymers of variable density is provided. The method involves making a bilayer roll 1 by laminating a layer containing a formulated polymer adhesive (component (2)) and a layer containing a non-woven fabric containing at least 50% recycled polypropylene resin (component (3)); making a trilayer roll 2 containing three laminated layers by laminating a layer containing a bioriented polypropylene (component (1)) and a bilayer from roll 1; making a trilayer roll 3 containing three laminated layers by laminating a layer containing a polyethylene foam having uniformly distributed air bubbles (component (4)) and a bilayer from roll 1; and making a multilayer roll 4 and a multilayer roll 5, each containing at least two selected from a bilayer from roll 1, a trilayer from roll 2, and a trilayer from roll 3. The multilaminate may contain five or more layers.
Spout pouch and method of making same
The present disclosure includes a process for making a package having a spout. The process includes heating a sealing area of a spout to a temperature at or above a melting point of the spout material; heating two multilayer structures around a portion of their peripheries to adhere the peripheries of sealant layers and form a partially sealed package having an opening; inserting the heated spout into the opening; and pressing opposing surfaces of the two multilayer structures around the spout to close the opening around the spout. Each multilayer structure includes a multilayer film having the sealant layer having at least 40% by weight of an ethylene-based polymer having a melting point below 112 C; an external layer including an ethylene-based polymer; and at least one intermediate layer disposed between the sealant layer and the external layer having a melting point at least 15 C higher than the sealant layer.
ANISOTROPIC THIN POLYETHYLENE SHEET AND APPLICATIONS THEREOF AND THE PROCESS OF MAKING THE SAME
This invention relates to an anisotropic multilayer film and the process of making a multilayer film, wherein a supercritical blowing agent is introduced to at least one layer, wherein at least one layer comprises 10 to 100 percent by weight LLDPE with a melt index of 0.2 to 2 g/10 min. The film in this invention can have a surface with an average Sheffield smoothness, according to TAPPI T 538, of less than 100. The film in this invention can have a puncture propagation tear resistance, in accordance with ASTM D2582, greater than 500 g/mil.
Fluid distribution material for absorbent articles
A fluid distribution material for use in an absorbent article includes a formed film layer, with a basis weight of between about 10 gsm and about 25 gsm, a user-facing side, and a garment-facing side. The formed film layer includes a plurality of apertured protuberances, numbering 10 to 40 per linear inch. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances, with land areas therebetween. A nonwoven layer, with a basis weight of between about 10 gsm and about 15 gsm, is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of fibers adjacent the land areas. Fibers adjacent the land areas are gathered a higher density than fibers located adjacent the plurality of apertures.
