 ● Pre-formed Pouches or In-line Formed retort able Roll Stock


Introduction:

The retort canning pouches are a flexible laminated packaging that can withstand thermal processing. It has the advantage of offering the shelf stability like metal cans, coupled with the nutrient value associated with frozen foods. The retort canning bags have been considered the most significant milestone in food packaging since the metal can achieved, and has the potential to become a feasible alternative to the metal can and glassware.


Advantages compared to metal can,

 ● Flexible pouches are more economy to distribute and therefore have lower logistic costs and require less disposal space.

 ● Storage space for empty flexible pouches is also reduced.

 ● The thinner material structure permits a reduced sterilizing time and faster transfer to its critical point and thus less of a chance to overheat the product while producing better layout. 

 ● Offers higher quality together with better retention of the heat-sensitive nutrients.

 ● The thermal process is complex and experienced data measuring due to the number of critical processing parameters which must be monitored (e.g., gram weight, residual air, pouch layers and RCPP thickness, steam/air mixture).

 ● Artwork designed can be printed into the laminate permanently. 


Characteristics essential to a satisfactory retort canning pouch are:

 ● Low oxygen permeability

 ● Low moisture permeability

 ● Resistant to penetration by fats, oils and other food components

 ● Physical strength to resist physical abuse (i.e., tearing, pin-holing, fatigue, impact and abrasion) during packing, retorting, storage and logistic

 ● Absence of solvent residues.

 ● Bonding materials for the laminates migration level must be within regulation.


Clear High Barrier Lamination:

We introduced the Japanese clear high barrier film since the year 2002 which technology brings food packaging more options for long shelf life, transparent retort available, microwavable pouches to replace foil pouch in food packaging solutions.
