Product Application : Vent Plug


When membranes and plastic parts are weldable together by ultrasonic or thermal method, a vent plug is created. With simple press-fit design, easy installation, and a long service life, it is suitable for large volume packaging (greater than 5L). Also, with an integrated design which ensures tightness and proper air permeability, it avoids pollutants from external environment, and maintains good air permeability even when in contact with high viscosity liquid, which greatly improves its reliability.


IPRO breathable membrane is suitable for agrochemical product packaging, and can be integrated with the injection molded parts of vent plugs to form standard parts. The models include D10/D15/D17/D38. IPRO also provides customized sizes and product types for client’s special needs.

  1. Be sure to check if the size of the vent plug is consistent with that of the cap. The tightness of the product depends on the material composition, structural design, sealing stability of the casing and the vent plug as well as the physical and chemical properties of the liquid in contact.
  2. PP and PE is recommended for casing material.
  3. Please avoid direct contact with or pressing against the membrane, avoid contact between the membrane and hard objects, and avoid placing the membrane on a high-temperature area. Improper operation may damage the breathable membrane and cause leakage.
