Milk is the finest resource of calcium for the body and also is a vital nutrient in people’s lives.

Milk packaging needs

In order to adjust to the demands of broadband automated milk loading equipments, milk product packaging films need to fulfill the complying with performance requirements during manufacturing.

 1 ). Slippery performance

The inner and also outer surface areas of the film must have good slip residential properties to make certain that it can continue efficiently on the high-speed automated filling up equipment.

2). Stretching efficiency

Given that the plastic film undergoes mechanical drawing force from the automatic filling up device throughout the filling process, the film must have adequate tensile toughness to stop deformation or being managed under the drawing pressure of the automatic filling machine

3). Warmth securing performance

Movie automated product packaging is one of the most concerned about leak of seal, incorrect seal, sticky knife and other problems causing broken bags, the much faster the filling speed warmth sealing requirements are higher.

4 ). Surface area moistening stress

The outside and interior surface areas of the film need to have good slip to make certain that it can be smoothly brought out on high-speed automated filling up equipments.

5 ). Obstacle efficiency

Product packaging products are required to have oxygen obstacle, light obstacle, wetness resistance, scent conservation, odor avoidance features, to choose barrier materials according to various components, rack life, production equipment, storage space problems, etc( 6 ). Needs for ink efficiency

Milk packaging movie is typically published by surface area printing, in addition to the basic technical needs of surface area printing ink, such as attachment, abrasion resistance and scratch resistance, as fluid milk product packaging, it should have the ability to hold up against pasteurization or hydrogen peroxide sterilization and also boiling treatment requirements, the ink has to additionally have oxidation resistance, water resistance, warm resistance as well as freezing resistance, in order to protect the movie in manufacturing, flow, transportation, storage and also other links The ink will certainly not diminish, blossom, condense, etc( 7 ). Security under heat

The security of the product packaging bag straight affects the safety and security as well as hygiene of dairy products. As a result of product packaging products, formulations, frameworks, refining help, manufacturing processes, other reasons and environmental problems, causing the decay of the active ingredients in the bag, movement, adsorption and also even chain reaction with the materials, which subsequently impacts the high quality of milk items, such as off-flavors, loss of milk flavor, delamination, modifications in tissue framework, and so on, and also trigger serious human side effects; or the bag in a particular temperature level water or milk immersion happens in the delamination The bag can additionally be made use of as a storage container for milk, contraction, decoloration, bond and various other sensations.

Benefits: outstanding gas and liquid obstacle, warmth resistance as well as chemical security; in enhancement, the rate is inexpensive, easy manufacturing process, can be recycled and also recycled often, can be made right into a range of gorgeous shapes and other benefits. In the previous couple of years, light-weight and also high-strength glass containers have been developed..

Tetra Pak packaging for milk.


” Tetra Pak” the primary element is cardboard, cardboard constructed from native long fibers, some of these fibers have been blonde and also some natural, in order to boost the thickness of the cardboard, the cardboard production procedure is typically included component of the chemical thermal grinding pulp (CTMP), in order to make the cardboard surface smooth and easy to publish, the exterior of the cardboard and a slim finish In order to make the surface of the cardboard smooth for printing, the beyond the cardboard has a slime layer. “Tetra Pak ” is a six-layer compound of cardboard, lightweight aluminum and also polyethylene foil.
