The seal liner has the characteristics of high temperature resistance, low temperature resistance, ozone resistance, aging resistance, corrosion resistance, oil resistance, etc. It can produce sealing gaskets of various shapes, including solid round gaskets or square gaskets and other shapes.

What is the function of seal liner?
Sometimes you need more than a lid to seal your container. A seal liner is a bottle cap sealant that can be found under the caps of a variety of bottled products, including ketchup bottles, windshield washer fluid, and more. The seal liner has several important functions:
prevent leaks
Preserve perishable products
as evidence of tampering
Some government agencies require products to have a seal liner. For example, the U.S. Food and Drug Administration (FDA) requires tamper-proof packaging for any over-the-counter product. Hazardous materials such as automotive fluids and other products may also require capping for safety purposes. Other groups, such as Amazon, are pushing more companies to equip their containers with these seals to improve shipping security. Whatever your needs, a feeling seal liner can make a big difference for your product.
What is the sealing film for?
"By adopting SAH/(SuperAnti-Humidity) and SAB/(SuperAirBalance) technology, our 001FV, 001MV and o01PV series seals have proven that they can work effectively not only to prevent the bottle from imploding or covering, but also to stop the penetrating moisture from entering the air into the sealed bottle!
For protein powders, pre-workout powders, products whose life guarantee is sensitive and moisture permeable, 001MV and FV seals have been highly recommended.
For tablets, capsules, pills whose products have been packaged with a canister whose diameter is less than 0.00 mm, 001NV seals are recommended.
What should we pay attention to when using seal liner?
1. When the working temperature of the flange is higher than 200 °C, sealant should be applied between the flange sealing surface and the seal liner to prevent the sealing gasket and the flange sealing surface from sintering at high temperature, which will increase trouble for maintenance and replacement of the sealing gasket.
2. If the sealing surface is uneven, you can apply sealant on the sealing surface and then install the seal liner. The sealant is generally composed of manganese dioxide, lead dan, graphite powder and linseed oil (drying oil) after being boiled. Liquid sealants of corresponding types and grades can be selected according to the sealing medium, working temperature and medium pressure.
3. For the installation of octagonal metal ring gasket, when the processing of the metal ring gasket and the flange sealing groove is not ideal, the close fit can be achieved by grinding. For large-diameter metal ring gaskets, it is difficult to match and grind. In order to fill the small unevenness on the metal surface, a sealant can be used.

The different sizes of gallon bottles allow the customer to choose different filling solutions. All products use food grade material.
The cap bottle is used for sealing the bottle. According to different functions, there are bottle caps with different shapes and different operation methods. For example, the cap of a mineral water bottle is round and twisted, the cap of a pop-top can is a ring, and the cap of a meat can is pulled.
Bottle closures are mounted directly from above by machine turning and tightened with the prescribed torque. Because the plastic has a certain elasticity, the inverted teeth in the anti-theft ring bounce back under the bottle caps and kink the flange of the bottle mouth after the bottle cap is mount
