Pressure-sensitive liners are designed as simple dust covers for dry capped products. They are not recommended for use with liquid products, packages requiring tamper evidence, or for those requiring an airtight seal to preserve freshness.<\/p>\n\n\n\n
The FDA defines tamper evident packaging as having one or more indicators or barriers to entry that provide visible evidence if tampering has occurred. Pressure-sensitive liners can be removed and reapplied without any visible evidence of tampering, making them unsuitable for tamper-evident purposes. Meanwhile, induction seals with the capability to leave a foil ring around the container lip, meet the tamper evident requirement effectively.<\/p>\n\n\n\n
The rise of e-commerce has also influenced a shift to induction sealing. Major online sellers like Amazon, and shipping companies such as FedEx, UPS, and the United States Postal Service have adopted guidelines requiring seals to prevent leaks during transit. An induction seal protects the product in the package while also preventing leaks.<\/p>\n\n\n\n
Unlike an induction seal, a pressure-sensitive liner does not create a hermetic seal to protect the product from oxygen and moisture transmission. Many packagers use induction sealing as part of their strategy to ensure consumers enjoy product freshness and quality.<\/p>\n\n\n\n
A key component of pressure-sensitive liners is polystyrene foam. In late 2023, major suppliers of polystyrene discontinued domestic production of polystyrene foam forcing suppliers to source materials offshore, leading to supply chain disruptions, increased cost, and quality concerns.<\/p>\n\n\n\n
Additionally, environmental legislation, such as statewide bans on polystyrene products, has further complicated the use of polystyrene in packaging. Many brand owners and packagers are hesitant to incorporate polystyrene foam into any new product package designs.<\/p>\n\n\n\n
Packagers moving to induction sealing from pressure-sensitive liners enjoy many benefits:<\/p>\n\n\n\n\n
