A focused material discussion
Choose materials for ISBM bottles around the project
Begin with the contents and expected service conditions, then assess the candidate resin and processing route. Do not select a material solely because a reference container looks clear, colored, rigid or flexible.
For ISBM bottles intended for food, cosmetics, laboratory or other regulated uses, request the relevant grade documentation and define the necessary testing. Resin names alone do not establish suitability for every formulation, filling temperature or cleaning method.
Where a specification is still open, list the requirements first: clarity, handling, chemical exposure, dimensional stability and any applicable compliance needs. This makes the discussion more useful than assuming that every image represents an approved material combination.
