Abstract
Sealing (peel seal) membranes for packaging aggressive or chemically reactive products such as hair colorants over long periods without seal failure are described. Advantageously, the membranes and other packaging components have a high resistance to chemical attack and exhibit other advantageous characteristics, such as good barrier properties that minimize or eliminate interaction with the external environment, chemical inertness with respect to the product, and desirable heat sealing properties for prolonged adhesion without cracking and/or product leakage. The membranes comprise an inner bonding layer comprising a blend of polyethylene (PE) with an anti-cohesion additive, and a barrier layer.
