.First, we need to understand where the name comes from. It was credited as a NASA invention to protect spacecraft from the sun's heat, and is now used in เว็บตรงสล็อต satellite communications and spacecraft. And here's a thought. What is the official name for the bags used in the home to preserve food and grains?
Actually "Mylar" is a well known brand of Printing Shell. ICI UK and Dupont USA were the first to apply for polyester film (PET) patents in 1984. They are made of a thin layer on a layer of aluminum-coated polyethylene terephthalate, or PET plastic. BOPET was developed in 1953 and BOPET bags were used in the kitchen at that time. As a result, many people refer to BOPET bags that are covered with compressed air as Mylar bags.
Absolutely, these are plastic packaging bags that are decided to be made from films, such as retort bags and vacuum bags. This extends the shelf life of foods, but will likely cost much less than a trained chef's storage room. When we say "mylar bags", we usually mean plastic packaging bags for food storage, made of silver and shiny BOPET film.
They have always had an excellent boundary with high temperature, lighting, relative humidity, breathable air, hydrocarbons and unpleasant odors. When these bags are used in conjunction with specially designed store buckets and oxygen absorbing materials, shelf life is greatly increased.
In addition, vacuum, proper cleaning filling, gamma rays, incredibly fast frozen and processed foods have become much more widely known in the field of food storage.
Coffee, nuts, cookies, chips, chocolate and cereal can be stored in Mylar bags. Unfortunately, in the absence of hydrogen or reflector, the period can be extended to 5 or 10 years. It does not make sense for a common person to store food for such a long time.
And besides, food is the first basic human condition after water. Our financial system may not always be stable, and environmental disasters, wars or terrorist attacks may occur. We need to focus on having a consistent diet already in case of an emergency. Sufficiently, proper storage is one of the scientific research projects of the federal government and researchers. These are some of the items to be researched and developed throughout the project, food packaging material.
• Preparation: long-term food storage in case of emergency
• Keep important paper documents such as house deeds, legal documents or cash
• Safe storage of photos, magazines, comic books, sports programs, postcards and books
• Hiking and camping
• Long-term storage of shoes and clothes
• Important medium-term storage of medicinal herbs and spices
• Sells tea and coffee packaging products
• Pharmaceutical and medical goods
• Car/car parts packaging
• Corrosion protection of iron objects such as nuts and bolts
• CD, vinyl and DVD storage
• Storage of firearms and weapons (with desiccant/silica gel packs that absorb moisture instead of oxygen)
• Storage for holidays
• Packing for the trip
The mass production method involves a film of polyethylene terephthalate (PET) in a liquid state that is extracted onto a frozen roll, which also cools it down to a water form. After being drawn, it is biaxially oriented.
During the week after reading the previous substance, you may have some questions about "mylar bags". Why do all the bags in the kitchen sparkle and shine? Are BOPET films transparent? Why? The materials used in the production bag for storage and preparation are actually BOPET coated on a metal surface equivalent to foil. As a result, as soon as you look at BOPET completely separately, it is transparent. But still, if we use "mylar bags" for food storage, a significant part of them is exposed to magnesium.
BOPET (Biaxially Oriented Polyethylene Terephthalate) is a thermoplastic film made from elongated PET used for its good strength, chemical and layer stability, clarity, absorption, oil and odor barrier properties and electromagnetic shielding. BOPET bags are becoming more and more popular, and the "Mylar" brand has reached more and more customers. Enough that we started calling them "mylar bags". By Printing Shell
