AeroPackaging Clear Natural Poly is a strong, clean all-purpose packaging film designed to balance good handling characteristics with an extremely clean surface. Available in standard thickness of .004″ and .006″ and custom thickness from .002″ to .008″.

Clear Natural Poly is one of the least expensive cleanroom packaging films available, while still supplying the highest level of performance. Fabricated from resin that is virgin (not recycled) and completely free of anti-blocks, slip agents and any other process aid. This, plus the quality processing procedures used for extrusion and manufacturing, ensures the highest-quality cleanroom bags available. Clear Natural Poly is used as a primary and/or barrier bag, and is an excellent choice because of durability, strength and ease of handling.

Standard items manufactured from Clear Natural Poly are clean to NASA JPR 5322.1-G (formerly NASA JPG 5322) Level 100.
