Abstract
The present disclosure relates to multi-layer film constructions and related methods. The multi-layer film constructions can include a first layer joined to a second layer. The first layer can include one or more heat resistant materials. The second layer can include a sealant film, which can be a multi-layer film having one or more sealing layers or sublayers. The sealing layers can include a blend of one or more ionomers and polybutylene. The multi-layer film constructions can also be free from or devoid of wax.
