Retort power device retort pouch) is one type of food packaging, classified as type flexible packaging (flexible packaging) made from the crazy house types. For welding (laminate) forming a bag (pouch) packaging sealed can close (hermectically sealed container).Can't stand the hot and high blood pressure. Used to contain the desired food sterilization by heating (thermal processing) level commercial sterilization like cans. Usually in autoclave sterilization under pressure (retort) type water spray retort.As well as canned food
.
the form of retort pouch
the form of retort pouch, there is either a bag. The bag set
materials, retort pouch
retort power and often materials thin plate เชื่อมประสาน (including many kinds of laminate)
.The material used as the main structure at the far end. Food contact directly is the most durable structure ที่หนา, high heat, high strength. Endure the pressure in the autoclave (retort)
.- Polypropylene (PP) a thick layer, inside the food contact directly used as a sealed ด้วยความร้อน
- Polyethylene. Terephthalate (PET) using in the form CPET
.Protective material permeability (barrier material) is the middle class used to prevent moisture, light and gas
- sheet feed EMS aluminum opaque appearance Prevent moisture, light and gas well
- crazy house EVOH sheet which prevent passing in and out of the gas well
.- nylon (nylon)
material outer layer (outer layer) is a federal emergency management agency, such as polyester sheet in the outer แรงทนท help strength, toughness. Heat resistance, and can print (printability) information or pictures on the Federal Emergency Management Agency have the advantages of retort pouch
.Food packing ในรีท is the power, light weight, easy transportation, packaging, lightweight, economical cost and space saving storage
strong. Not broken, easy
.A flat shape. The surface area per volume than the area of heat transfer ร้อนแทรก through a lot better. Take the time to sterilize heat (thermal processing).Or glass bottles, in addition to spend less, help make sterilization treatment food quality aspects, such as a color, flavor, texture of the food better. Suitable for food sensitivity to heat, such as curry paste
.Print color photos, information, a beautiful, attract consumers onto the surface.
.To open the bag to take out food easier than the metal can. Especially if the bag is cut to help in the open. The open bag with his bare hands. Without the use of tools or devices to help
.Test equipment explosion (burst tester) or tensile testing (tensile test) to evaluate and control the quality of leaders in power in street
strength testing of the retort power.

.Limitations of retort pouch
have relatively high investment introduction, such as sterilization machine (retort)
.Control of heat treatment process for sterilization are complicated. Such as the need to control the amount of air remaining in the bag or bags. The thickness of side of the envelope. A mixture of steam and air in air disinfection.To lack of circulation and distribution of heat within such a
.The envelope or bags are often pierced or tear easily. Need to rely on the protection of the outer container such as paper box, another layer to achieve the safety during transportation
