SPE safe Vent 5 layer induction wads are used for sealing PET bottles & HDPE bottles containing chemicals that give off vapours and create high or low-pressure conditions inside the container. To keep the seal integrity, a membrane vent is inlaid within the wad which helps in equalizing the pressure inside the container while still maintaining a tamper and contamination-proof seal.

Due to breathable property SPE safe Vent 5 layer induction wads are highly recommended for use in food industry, chemical industry & pesticide industry. They have high chemical resistance, moisture resistance, corrosion resistance, pressure resistance & seal strength. Typical breathable induction vented wads are made of heat seal material, pet, aluminium foil, wax and pulp board with membrane inlay. The structure, strength & thickness of vented induction wads can be customised by changing layer structure of the laminate.

Significant Features:

Innerseal Structure: Heat Seal/PET / Alu / Wax / Paperboard with membrane filter

Bottle Material: PET / PE-containers

Seal Feature: Weld Seal or Temper Seal

Applications: For Pesticides, Agro Chemicals

Frequently Asked Questions:

1. Q: What happens if a normal 5 layer wad is used instead of a SPE safe Vent 5 layer induction wad?

   Ans: The buildup of gases within the container causes swelling and deformation which may lead to leakage.

2. Q: What are the critical factors in selecting type of breathable vented induction wads?

   Ans: The selection of breathable vented induction wad is related to the nature of packaged liquid, sealing strength required, size of the container neck, vapour venting requirements, etc.

3. Q: Is there chance of leakage from through the membrane inside the wad?

   Ans: No
