Hydrophobic High Airflow PE Foam Vent Seal Liner


Description

 
Breathable PE foam vent liner provides air exchange and pressure balance for containers and bottles. Ideal for food, chemical, cosmetic, and household packaging to prevent leakage and deformation.


1. Product Overview

Our PE Foam Vent Liner is an innovative sealing solution designed for modern bottle packaging systems, combining reliable sealingmoisture resistanc, and controlled breathability. Made from high-quality polyethylene foam, the liner features a uniform micro-cell structure with excellent elasticity. By integrating a micro-porous vent membrane or functional composite layer, it allows controlled air exchange while maintaining a secure seal — effectively balancing internal and external pressure to prevent leakage or container deformation.

2. Technical Features

  • Excellent Sealing Performance – The PE foam layer provides stable compressive resilience for tight and consistent sealing.

  • Pressure Balance Venting – Built-in micro-vent structure equalizes pressure differences caused by temperature changes or transportation.

  • Moisture & Contamination Barrier – Prevents external moisture, dust, and contaminants from entering the container.

  • Chemical Resistance – Resistant to acids, alkalis, oils, and a wide range of chemical formulations.

  • Lightweight & Eco-Friendly – Fully recyclable materials, compliant with RoHS and REACH environmental standards.


3. Bottled Products Applications
