Cling film or cling wrap is a thin plastic film primarily used at homes, offices, and restaurant kitchens to seal and secure foot items in containers. By sealing with cling wrap, food doesn’t lose its freshness. A cling wrap or cling film comes in a roll in a box that has a sharp edge for cutting the wrap.
A cling wrap is a household and office essential. It seals everything perfectly, reducing the chances of an accidental spill. It was discovered in 1933 initially in the form of a spray to be sprayed on fighter planes to protect them from the salty sea spray. However, the original wrap was invented in 1949. It was a Polyvinylidene Chloride (PVdC). Nowadays, PVC alternatives are popular among buyers because these are considered to be a safer option from a health perspective.
Making of a Cling Wrap
Step 1: Heating plastic granules till they melt.
Step 2: The molten liquid is poured through a die to make a stretchable tube of plastic.
Step 3: In the next step, compressed air is blown into tubes to form bubbles.
Step 4: When the bubble forms, it stretches the plastic.
Step 5: The stretched bubble is put between metal rollers for forming a film.
Step 6: The film is rolled, and the rolls are put in cardboard packaging
The cling wrap that is found in the store is of 35ga to 40ga thickness.
