Abstract
Multilayered sheet (I) comprises (a) an exterior heat sealable layer; (b) a first adhesive layer; (c) a barrier layer; (d) a second adhesive layer; (e) an oriented polypropylene (OPP) layer; and (f) a polyethylene layer. Layer (e) is 0.65-2.0 (0.75-2.0) mils thick and layer (f) is 0.7-3.0 mils thick. Layer (a) is mainly LLDPE (linear low density polyethylene) of 0.7-3.0 mils thick. This sheet (I) pref. also has layers (g) paper; (h) a second polyethylene; and (j) a second exterior layer, layers (h) and (j) being 2.0-5.0 mils thick with good adhesion. (I) has improved stress crack resistance with improved resistance to shock abuse. It is for use in forming tubes esp. for paste materials e.g. toothpaste. (Provisional Basic previously advised in Week 83/44).
