ASTM D4635

ASTM D4635 is the ASTM standard specification for plastic films made from low-density polyethylene and linear low-density polyethylene for general use and packaging applications. It provides a technical basis for describing these films in a consistent way, helping buyers and suppliers align on material expectations and product quality. For packaging and general-purpose film applications, this specification can support clearer procurement, product evaluation, and compliance discussions while keeping the focus on the polyethylene film types named in the standard title.

Purpose of ASTM D4635

The purpose of ASTM D4635 is to define a specification framework for plastic films produced from low-density polyethylene and linear low-density polyethylene. As a standard specification, it is intended to help establish a common reference for these materials when they are used in general-purpose and packaging applications. That makes it useful for communicating requirements, comparing products, and supporting quality control where film consistency and material identification matter. It is centered on the film types identified in the official title.

Common use cases of ASTM D4635

This standard is commonly relevant when specifying polyethylene films intended for general use or packaging-related applications. It may be used by manufacturers, converters, distributors, and purchasers who need a shared technical reference for low-density polyethylene and linear low-density polyethylene film products. In practice, ASTM D4635 can support product selection, purchase specifications, incoming inspection, and other workflow steps where film material classification and consistent performance expectations are important.

Why ASTM D4635 matters

ASTM D4635 matters because it helps create consistency in the specification of polyethylene films used in everyday and packaging applications. A clear standard can reduce misunderstandings between trading partners, support more reliable product comparisons, and strengthen quality control programs. It may also help organizations evaluate compliance more efficiently and reduce risk when sourcing film materials. For teams that depend on predictable film characteristics, the standard provides a practical technical reference tied to the material types in its title.
