Amcor Unveils Moderna Flip Top Closure
The recycle-ready, one-piece closure for vinegar, sauces, and dressings adds a tamper-evident seal and one-handed opening.
Updated on Nov. 6, 2026 in Consumer Goods
Amcor has introduced the Moderna Flip Top, a tamper-evident closure for vinegar, sauces, and dressings. The recycle-ready monomaterial closure is built as a single piece and includes an integrated tamper-evident seal that shows whether a product has been previously opened.
Why it matters
The closure is designed to meet consumer expectations for convenience and sustainability while using less material than conventional closures. Its lightweight design can help companies comply with plastic packaging regulations.
The Moderna Flip Top is engineered for a 29/21 neck finish and offered in 2 mm, 6 mm, and multi-orifice sizes, according to the manufacturer's specifications. The extraction provides no comparator for material savings, and no customer adoption figures have been disclosed.
The players
Amcor
Amcor is a global packaging company that supplies flexible and rigid packaging solutions to food, beverage, healthcare, and consumer goods brands.
The details
The closure opens with one-handed actuation, allowing controlled pouring or dispensing, and the tamper-evident tab is captured within the closure body after opening. It includes a snap-on application for integration with PET bottles and comes in a range of standard colors.
Timeline
Amcor's Moderna Flip Top closure announcement was published on November 6, 2026.
Market Landscape
Amcor previously equipped Vöslauer Mineralwasser with a tethered cap earlier this year, and the Moderna Flip Top extends that approach into vinegar, sauce, and dressing packaging. Its partnership with Wattwiller on a lightweight, ergonomic closure points to a broader push by packaging suppliers to pair tethered and tamper-evident designs with lower material use.
Shoppers buying vinegar, sauces, or dressings in bottles fitted with this closure would see a tamper-evident seal and a tab that stays attached after opening. Brands adopting the closure could make these features available on store shelves, though the extraction does not confirm any retail rollout.
The takeaway
Tamper-evident seals that stay attached after opening address both tampering concerns and waste reduction in one design. As regulators and consumers press for recyclable packaging, closures that use less material may become a standard expectation for condiment and dressing bottles.
