Technical Strength

Shield against oxygen, seal in freshness like amber

Using CNC nanocellulose to build a high-barrier layer, the barrier remains intact after retorting; every parameter is sent for third-party testing, and report numbers are traceable.

Core technology

CNC nanocellulose high barrier layer

Plain-language explanation

CNC (cellulose nanocrystals) is a nanoscale material extracted from plant cellulose, featuring a dense crystalline structure. Introducing it as a functional layer into a multilayer film structure is like installing an "oxygen barrier shield" on the packaging: oxygen molecules struggle to penetrate it, and since the structure does not absorb water, its barrier performance remains stable even after 121°C retorting.
Professional Edition Description

Xindun combines a CNC nanocellulose core functional layer with multi-layer lamination technology to produce food packaging film that is high-barrier, high-temperature resistant, transparent, and microwaveable. The company has full mass production capabilities spanning functional layer preparation, multi-layer lamination, and roll film slitting. Every batch undergoes quality inspection before leaving the factory, with key indicators sent to third-party labs for testing, and report numbers are traceable.

Aluminum foil is opaque and cannot be microwaved; PVDC contains chlorine and poses environmental risks; EVOH loses barrier performance after retorting when exposed to moisture. Xindun CNC film is transparent, microwavable, stable after retorting, chlorine-free, and recyclable, making it a high oxygen barrier alternative for high-temperature sterilization packaging.
