About This Item
ASTM D7611/D7611M is the ASTM standard that covers the coding of plastic manufactured articles for resin identification. It is used to help identify plastic materials in a clear and consistent way, supporting sorting, recycling, and product communication. As a technical reference, this standard matters because it helps manufacturers and users apply resin identification markings more uniformly, which can improve material handling and reduce confusion across the supply chain.
Purpose of ASTM D7611/D7611M
The purpose of ASTM D7611/D7611M is to provide a standardized practice for coding plastic manufactured articles so the resin type can be identified in a consistent manner. The official standard title indicates a focus on resin identification, which is important for organizations that need a common method for marking plastic items. This ASTM standard is generally used to support clearer communication about material type and to help align identification practices across products and operations.
Common use cases of ASTM D7611/D7611M
ASTM D7611/D7611M is commonly referenced when plastic articles need resin identification coding for handling, recovery, or downstream processing. It is relevant to manufacturers, converters, and other users involved in producing or marking plastic products where material identification is important. The standard may also be used in quality control or product documentation workflows when a consistent coding practice is needed for plastic manufactured articles.
Why ASTM D7611/D7611M matters
This standard matters because consistent resin identification can support compliance efforts, product evaluation, and better material management. Using ASTM D7611/D7611M can help reduce ambiguity when plastics move through manufacturing, distribution, or recycling-related workflows. For procurement and quality control teams, a recognized ASTM standard provides a clearer technical basis for checking whether identification markings are applied in a uniform and reliable way.
