What Are Pressure Sensitive Liners
Pressure Sensitive Liners help you seal jars and containers without extra equipment. These liners use a special adhesive to stick to the rim of your jar. You can use them with glass or plastic containers. They work well with lined or unlined caps. Their main job is to keep dry products safe and fresh.
Tip: You do not need machines to apply these liners. Just press and twist the cap onto the jar.
Here is a quick look at what makes Pressure Sensitive Liners unique:
| Definition | Primary Function |
|---|---|
| Pressure sensitive liners are polystyrene foam disks with an adhesive layer at the bottom. | They create a seal suitable for dry products without requiring additional equipment for application. |
How They Work
You activate the liner by screwing the cap tightly onto the jar. The pressure bursts tiny bubbles in the adhesive. This action releases the glue and sticks the liner to the rim. You get an airtight seal that keeps out air and moisture. The seal also shows tamper evidence. If someone tries to open the jar, the liner creases and makes tampering easy to spot.
Steps to apply a pressure sensitive liner:
- Clean the rim of your jar.
- Place the liner on the rim.
- Screw the cap on tightly.
- Wait 24-48 hours for the seal to set.
Types and Applications
You find different types of pressure sensitive liners in the market. Most use foam or paper backing with an adhesive layer. The key part is the adhesive, which works best for dry products. You should not use these liners for liquids. They fit many products, such as spices, vitamins, cosmetics, and pharmaceuticals. You can use them with both glass and plastic jars.
Note: Pressure Sensitive Liners do not meet FDA tamper-evident rules, but they still help you spot tampering.
You get a simple, effective way to protect your products and give your customers peace of mind.
Why Pressure Sensitive Liners Matter
Preserve Freshness and Prevent Contamination
You want your products to stay fresh and safe. Pressure Sensitive Liners help you do this. These liners use a special glue that seals out air and water. When you put the liner on, it makes a barrier.

You do not need machines to use these liners. You get a tight seal every time. This seal helps stop contamination and keeps things fresh longer.
Tip: Make sure the liner is flat on the rim before sealing. This step gives you the best protection.

You avoid spills and waste. This saves you money and keeps shelves clean. The liner also blocks oxygen and gases. Oxygen can make products stale or lose flavor. Keeping oxygen out helps your products stay fresh. These liners work best with dry products. They may not seal well with liquids or in humid places.
