Description

The PE Aluminum Foil Venting Liner provides excellent pressure balance and moisture protection for bottled products.
It is widely used in packaging for pesticides, liquid fertilizers, disinfectants, and pharmaceutical formulations, where high sealing performance and stability are required.
The built-in controlled venting system effectively balances internal and external pressure, preventing bottle bulging, leakage, and liquid overflow caused by gas expansion or contraction—ensuring safe and reliable product storage and transportation.

1. Product Overview

The PE Aluminum Foil Venting Liner is specifically engineered for modern bottled product packaging,
offering an intelligent sealing solution that combines airtight protection, moisture resistance, and controlled breathability.

Constructed from high-quality polyethylene laminated with aluminum foil and PTFE micro-venting film,
this liner maintains optimal pressure equilibrium while preventing leakage or bottle deformation caused by gas expansion or contraction.

Its precision venting system allows air exchange while blocking liquids and moisture ingress,
ensuring stable performance under temperature fluctuations and transportation conditions.

Ideal for pesticides, liquid fertilizers, disinfectants, pharmaceutical formulations,
surfactant-based liquids, and various additive products,
this liner provides dependable protection and long-lasting freshness throughout the supply chain.
