After retorting, the barrier remains as good as new: Xindun Technology unveils its brand proposition, replacing aluminum foil and PVDC with transparent high-barrier solutions.

Guilin Xindun Technology Co., Ltd. officially releases its brand proposition — "After retorting, barrier as before". This statement conveys one thing: after retorting, OTR still stays below <1 cc/(m²·day·atm). This is the core difference that sets Xindun apart from all transparent barrier solutions, and it is also what food companies care about most — "can it still keep food fresh after sterilization?"

Replacing three types of traditional high-barrier systems

Xindun builds a high-barrier layer with bio-based nanocellulose: compared with aluminum foil (opaque, microwave-prohibited), the XD series is both barrier-effective and transparent, balancing shelf display with microwave heating convenience; compared with EVOH/AIOX (barrier performance decays after retorting), XD-121 maintains OTR at 0.4→0.5 before and after retorting; compared with PVDC (chlorine-containing, difficult to recycle), the XD series is chlorine-free and bio-based, aligning with ESG and the EU PPWR recyclability trend, making it especially suitable for brands with export markets in Europe or green procurement policies.

Five commitments to customers

Reliable barrier, no compromise at high temperatures: OTR remains stable before and after retorting, and shelf life claims are backed by physical evidence; transparent and microwaveable: replaces aluminum foil, enabling both shelf display and end-user heating; safe and compliant: no metal migration, food contact safety, supporting PVDC replacement; stable production: puncture resistance 11.1N, thermal shrinkage TD only 0.1%, reducing bag breakage and downtime losses; factory-direct supply, customized on demand: supports width/length/thickness customization and small-batch trial production, with controllable lead times.

Xindun serves B2B food processing enterprises in high-temperature sterilization categories such as meat, braised food, cooked food, nuts, wet pet food, and baby food. We speak with testing data and do not promise unverified metrics — this is Xindun's character, and also the confidence behind "After retorting, barrier as before."
