Peelable Coupon Containing Printable Water-Based Acrylic Pressure Sensitive Adhesive
The present invention is directed to a packaging article configured as packaging rollstock comprising a multilayer laminate having an integrally formed peelable, removable coupon. The coupon is formed from a first layer having at least two score-lines and a pattern-applied second, third, fourth and fifth layer. The coupon includes an interior printable water-based acrylic pressure sensitive adhesive layer which advantageously provides a surface for printing graphics and resealability to packages made there-from.
RE-SEALABLE PACKAGES WITH INDEPENDENTLY PEELABLE LIDDING MEMBER PORTIONS
Improved packages and methods for constructing packages are provided that are designed such that the user can peel back a lidding member of the package to reveal an independently peelable portion covering one of the compartments. The independently peelable portion is a layer of the lidding member that maintains the respective compartment in an unopened (sealed) condition until the user independently peels that layer off to access the items in that compartment. The lidding member can be used to re-seal all of the compartments before and/or after the independently peelable portion is removed. The independently peelable portion may include a visual indication of a sealed condition of the compartment that serves as a tamper evidence feature. In multiple-compartment packages, peeling back the lidding member allows the user to access some of the compartments of the package, while at least one of the compartments remains sealed via the independently peelable portion.
Packaging Laminate
Disclosed herein are compositions and methods related to a packaging laminate comprising: a first polymeric layer comprising a polypropylene copolymer; and a second polymeric layer comprising a high density polyethylene (HDPE) resin with a coextruded ethyl vinyl alcohol (EVOH) compatibilizer.
FLOOR CLEANING ARTICLE HAVING STRIPS WITH DIFFERENTIAL BOND PATTERN
A cleaning article. The cleaning article has a laminate construction. The cleaning article comprises a sheet and a hydrophilic gather strip element joined together at plural bonds. The gather strip element has plural layers superimposed upon one another, providing strips extending outwardly from the bonds. Different layers are differentially bonded, to provide a construction which allows the strips to advantageously present a dynamically changing area to the target surface during cleaning, under normal usage conditions. By changing the surface area, more liquids, and associated debris, can be cleaned from the target surface.
EASY-OPEN RECLOSABLE FLOW-WRAP PACKAGE
The present invention is directed to a peel-open, reclosable package formed from a single thermoplastic laminate comprising a first film laminated to a second film. The package includes a peelable, resealable heat-seal seam adhering an interior surface of a first sealing section of the interior package surface to an interior surface of a second sealing section of the interior package surface. The package also includes an asymmetric cross-sectional seal interface formed at the peelable, resealable heat-seal seam by disjoining a segment of the first film from the first sealing section prior to heat sealing the first and second sealing sections together.
BOPP MULTILAYER FILM
A BOPP multilayer film having at least three layers made from or containing a nucleated propylene polymer composition having: A) from 77 wt % to 91 wt %, of a propylene homopolymer having a fraction insoluble in xylene at 25° C. higher than 95%; B) from 9 wt % to 23 wt %, of a copolymer of propylene with from 28.0 wt % to 42.0 wt % of ethylene derived units; and C) a nucleating agent selected from aromatic or aliphatic carboxylic acids, aromatic metal phosphates, sorbitol derivatives and talc, wherein the composition has an intrinsic viscosity (IV) of the fraction soluble in xylene at 25° C. between 1.0 dl/g and 1.9 dl/g, a fraction soluble (Xs) in xylene at 25° C. between 9.0 wt % and 21.0 wt %, a total melt flow rate (MFR) between 1.5 and 5 g/10 min and the value of the relation (I):
22.5+0.2*MFR−1.2*Xs+0.2*IV (I) higher than 5.9.
BELT OR FABRIC INCLUDING POLYMERIC LAYER FOR PAPERMAKING MACHINE
A fabric or belt for a papermaking machine including a first layer that defines a web contacting surface and a second layer that supports the first layer. The first layer is made of extruded polymer and includes a plurality of first elements aligned in a first direction, a plurality of second elements aligned in a second direction and extending over the plurality of first elements, and a plurality of open portions defined by the plurality of first and second elements. The second layer is made of woven fabric. The first layer is bonded to the second layer so that the first layer extends only partially through the second layer and an interface formed between the first and second layers includes bonded and unbonded portions and airflow channels that extend in a plane parallel to the first and second layers.
Latent elastic composite formed from a multi-layered film
A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from a multi-layered, elastic film laminated to a nonwoven web facing. Latent elasticity is imparted to the composite through the use of at least one base layer that contains a thermoplastic elastomer and at least one skin layer that contains a propylene/α-olefin copolymer. During formation, the film is stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the propylene/α-olefin copolymer. The stretched elastic film may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated at or above the softening point of the copolymer) to soften the crystalline domains and allow the chains to return to their unoriented state. This causes the film to retract, which forms buckles in the nonwoven facing. In this manner, the resulting composite becomes elastic in that it has the ability to stretch and recover due to the “latent” buckle formation in the nonwoven facing.

Multilayer Thermoplastic Film with Improved Puncture Resistance Performance
The present disclosure provides for a heat-shrinkable, biaxially stretched, multilayer thermoplastic film that includes at least a puncture resistant layer. The puncture resistant layer is formed with a polyethylene based plastomer having a density of 0.890 g/cm.sup.3to 0.910 g/cm.sup.3 as measured in accordance with ASTM D-792, and a melt index (MI) as measured by ASTM D-1238 at 190° C./2.16 kg from 0.20 g/10 minutes to 1.5 g/10 minutes. The polyethylene based plastomer has a log M.sub.25% of an upper 25% of a GPC quadrant having a value of 5.1 to 5.7, an intermediate molecular weight distribution (Mw/Mn) of 2.5 to 3, a Mz/Mw value of 2 to 2.5, a Comonomer Distribution Constant value from 60 to 400 and a single SCBD peak between 40-85° C. with a mass fraction of less than 3% above 85° C. as determined by CEF, and a ZSVR value from 1.0 to 5.5. The multilayer thermoplastic film is biaxially stretched at a temperature of 60° C. to 120° C. with a blow-up ratio from 2:1 to 10:1.
