Global packaging company Sonoco has expanded its ClearGuard flexible packaging range to include pouches for liquid or more viscous products.
The newly introduced product line will be able to endure hot fill and retort cooking processes.
Sonoco marketing director Pete Gioldasis said: “Our ClearGuard portfolio of structures has already helped multiple customers achieve success with applications like trail mix, jerky and snack bars.
“And with this latest technical development, we’re now able to expand the portfolio to include highly engineered structures capable of withstanding more demanding applications, like fitment pouches that perform in hot fill or retort processing conditions.”
The company noted that ClearGuard packaging protects the food inside and preserves its shelf life due to its low oxygen and water vapour transmission rates.
The packaging can be used as an alternative to aluminium foil or metalised films.
