Who created the zip lock bag
You must have noticed when you tear off a plastic bag from its roll in a supermarket, the end of the other plastic bag pops open. We thought it is a natural phenomenon.
A very important process called the corona treatment treating plastic with plasma or superheated charged air is the reason behind this trick. Also, it makes the plastic to hold ink, for stamping logos. Your plastic bag is ready. Oh, wait. Are you sure it can hold so-many-ounces-of goods? Why not give it a jog test? A jog test is performed by a machine where a plastic bag is filled with ginormous amounts of weight, and then mounted on the machine.
The machine bobs the plastic bag up and down times! All this is done to test whether you can jog or run up to your car carrying your groceries. And you were saying it is such an easy job? This is not even the end of it. You forgot to attach the zipper, which makes this kind of bag re-sealable, and not to forget complete the extremely complex design.
There are two types of zippers which are used, making two different types of bags. The Ziploc engineers have taken the pain to nail its design and believe me it was not a not a cake-walk. The zipper has microscopic J-shaped grooves on one side of the sheet which fits into the arrowhead-like depressions on the other sheet. When you run your fingers over the track to open the bag, all you do is unclasp these grooves. Sometimes we are just too lazy to align it properly and then seal it.
That lets in the most dangerous thing known to ziplock engineers. It is the reason behind your food going stale. Steven Ausnit, founder of the company Flexigrip and developer of the original Ziploc, recalled one incident from the early s.
He had persuaded Columbia Records to give a plastic bag with zipper a shot for storing albums. They asked a lady to do the honors of opening a sealed bag and instead of opening the zipper, she tore it right off the bag.
The researchers must have understood our struggle and so, came up with the idea of protruding a quarter inch of tab from the lip of the bag, making it more graspable. Now, no more fighting with the bags! Plastic has always been the hot topic of discussion, all because of the non-renewability of its source.
This is where Ziploc comes in. Well clearly, you can reuse them but they do not like being washed and often get damaged. One worried mother, who got tired of buying these bags, created a new food-grade bag known as Neat-os. While S. Today IMPAK provides stock and custom packaging with unique zipper profiles paired with a range of materials. This allows us to deliver resealable, protective packaging for sensitive products, from food to medical test samples.
These zipper styles are readily available on stock products; if not readily available, they can be used in conjunction with our pouch making machinery. We can run test and production quantities of almost any zipper profile in the marketplace. Some challenges are not solved by the type of zipper, but by the material that the zipper requires to mate with other custom laminations, a particular skillset of IMPAK. For example, we offer pouches made from high temperature materials designed to safely cook contents inside the package, commonly used for packaging tuna and salmon.
The challenge here for the flexible converter on a multi-use pouch was providing a material that would withstand that temperature and still maintain the water-tight seals. Unsurprisingly, the development of a package in which the product would be cooked in the bag required significant testing on extractables, and the ability to withstand autoclaving and not impart any component of the packaging material to the food product.
This press to close zipper style employs a single piece of material which protrudes from the pouch and fits directly into a track on the opposing side of the pouch. Interlocking plastic pieces snap into place and create friction to prevent the zipper from opening. This is the most commonly used profile and it is applied to pouches from standard clear zipper bags to Mylar foil zipper bags.
Max Austin and Edgar Austin were great Romanian industrialists who owned several steel and munitions businesses. They were very well known for their businesses. These bags have evolved the food packaging industry, as it solves the biggest problem of food storage, providing Air lock which keeps the food fresh and prevents spoilage.
