How To Choose The Right Pressure Sensitive Seal Liner

Selecting the proper pressure sensitive seal liner is crucial for ensuring the sealing function and preservation against leaks in any packaging container. With a variety of types and features available on the market, understanding the differences is key to making a wise decision. The main PE Foam pressure sensitive liners include standard seal liners, film-coated seal liners, and pure aluminum seal liners. This guide will lead you through the key factors to consider when choosing the perfect pressure sensitive seal liner to meet your specific needs.

Types of Pressure Sensitive Seal Liners:

Standard Domestic Pressure Sensitive Seal Liners

Standard domestic pressure sensitive seal liners are widely popular due to their cost-effectiveness and ease of use. These liners do not require machinery for sealing and are used for dry food, pharmaceuticals, cosmetics, etc., providing reliable leak-proof and fresh-keeping performance. They are available in 0.9mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 2mm thicknesses.

Aluminum-Coated Pressure Sensitive Seal Liners

Aluminum-coated pressure sensitive seal liners have greater adhesion than standard domestic seal liners. A layer of aluminum foil is coated on the surface of the liner, providing excellent sealing properties that can effectively prevent gas and steam penetration, which is particularly important for products requiring long-term preservation. In addition, the aluminum layer can provide a physical barrier, resisting puncturing and tearing, used for products that require a higher level of protection.

Imported Pressure Sensitive Seal Liners

Imported pressure sensitive seal liners can be as thin as 0.6mm, and while thinner than standard liners, they do not compromise on sealing or adhesiveness. They use higher quality materials and adhesives, ensuring safety and sealing.


How To Measure and Choose Pressure Sensitive Seal Liners

Measuring Dimensions

  • Determine the Inner Diameter: Measure the inner diameter of the container mouth to ensure the liner fits accurately.
  • Thickness Requirement: Select the appropriate liner thickness based on the product’s fresh-keeping and leak-proof requirements.
  • Consider the Shape of the Container: The shape of the container may affect the choice of liner size, such as the slope of the bottle neck.


Choosing Pressure Sensitive Seal Liners

  • Application Consideration: Consider what type of product the liner will be used for. For food, pharmaceuticals, and cosmetics, safety and preservation are primary considerations.
  • Environmental Factors: If the product will be exposed to extreme temperatures or chemicals, choose a liner that can withstand these conditions.
