In the plastic packaging industry, pressure-sensitive liners have become increasingly popular for health supplements and food packaging due to their easy application and no need for heat sealing. These liners adhere to the bottle mouth when the cap is tightened, forming a basic seal without requiring any heat-sealing equipment.
They are particularly suitable for room-temperature filling and products that don't require long-term preservation. Pressure-sensitive liners work well with PE and PP bottles and offer a cost-effective sealing solution.
However, it's important to note that they are not ideal for products that require high-temperature filling or extended shelf life, as their sealing strength is moderate.
