Today there was a drizzle, small make up one hand all the way on a HELLO to a company.
Just sit down and think of today to popularize knowledge of
food packaging materials under small for you.
And introduce today is nylon membrane material, good, cut short, the following: to get down to business of food packaging material nylon membrane.
A, food packaging material nylon membrane characteristics summarizes nylon membrane, referred to as 'PA, scientific name polyamide membrane, it is a kind of abnormal tough material.
Advantages as follows: transparent luster, strong tensile, tensile, heat, cold, puncture, such as the environment, to oil, organic solvent, oxygen resistance, good printing adaptability good;
But there are also disadvantages: moisture absorption moisture permeability, heat sealing ability is poor.
Second, the classification of food packaging material nylon film is currently in use of nylon film brands on the market has a lot of, such as nylon 6, nylon 66, nylon 11, nylon 12, nylon, such as copolymerization of nylon 6 is the most used in food packaging.
Like a lot of film, nylon according to is divided into BOPA film way, OPA, PA.
Three application in the food packaging bags, nylon membrane materials in nylon bags of at ordinary times we used to say, is the nylon membrane material compounded with other film.
Nylon film composites are often made cooking bags, high temperature sterilization bag transparent vacuum bag.
Nylon bags used very much, but different in the field of food packaging, see the advantages of the nylon membrane material has a slightly different: 1, frozen food packaging, seeing the nylon membrane is a good cold resistance, high tensile strength to be able to adapt to the heat bilges cold shrink.
Commonly used to package seafood, fish, pork meatball, dumplings, dumplings, etc.
2, fat meat seasoning bags and food bags, they choose nylon membrane material, because grease, organic solvents is difficult to through the nylon membrane, and not easily punctured.
Such as sauce package of instant noodles, chicken legs, chicken feet, etc.
3, cooking food packaging bags, seeing the nylon membrane material is a good gas barrier property, oil resistant, high temperature, puncture;
Think we see hot pot bed charge, tempeh, etc.
Four, nylon film and other film difference from several transparent film, nylon film will pick out, just from the appearance, to feel the difference, a little more difficult.
We can put film in warm water, and then pick up the, the variation before and after the film hardness is the nylon membrane.
This distinction method, is to use the moisture absorption characteristic of the nylon film, nylon after absorbing water become more soft.
Above is the small make up summary of food packaging material nylon film knowledge, hope you like them.
If you like, you point under the lower left corner, share it.
Let more people to become familiar with understand food packaging material.
