A custom underlayment film program starts with the application.
Under-slab water and gas barrier film for concrete applications and construction-grade protective requirements.
Underlayment film can be specified around barrier performance, toughness and installation needs for slab and construction environments.
PKG develops underlayment film by looking at the full packaging system: what the product must survive, how the film or bag runs through jobsite installation, concrete placement, slab protection and bulk roll handling, and which quality checks are needed before the material is released for production.
The result is a practical, engineered film conversation for construction, under-slab and barrier applications that need tough plastic substrate performance where resin selection, gauge, layer structure, conversion format and commercial requirements are evaluated together.
For building and construction applications where film performance is critical, small specification choices can determine whether a package loads smoothly, seals consistently, protects the product and arrives in the expected condition. PKG positions underlayment film as a custom packaging solution rather than a one-size-fits-all catalog item, with each request reviewed around production reality, quality expectations and commercial volume.
