What is polyethylene film?
PE Film is a plastic film made from ethylene, a hydrocarbon which is mainly obtained from natural gas or petroleum. The terms ‘plastic sheeting’, ‘polyethylene sheet’, ‘poly sheeting’ or ‘poly film’ are often used as synonyms for polyethylene film.
The term polyethylene is abbreviated as ‘PE’, the same way polystyrene and polypropylene are abbreviated as ‘PS’ and ‘PP’ respectively. In the United Kingdom, the word ‘polythene’ is often used instead of ‘polyethylene’.
What types of polyethylene film are there?
PE Protective Film can be made of different types of polyethylene. The most sold types of polyethylene are:
Low-Density Polyethylene (LDPE).
High-Density Polyethylene (HDPE).
Linear Low-Density Polyethylene (LLDPE).
Polyethylene film can also be manufactured in different colours or be transparent. In addition, it can be purchased in different thicknesses.
Aluminum Foil is a common household product that’s often used in cooking. Some claim that using aluminum foil in cooking can cause aluminum to seep into your food and put your health at risk. However, others say it’s entirely safe to use. This article explores the risks associated with using aluminum foil and determines whether or not it is acceptable for everyday use.
What Is Aluminum Foil?
Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
Commercial Aluminum Foil is used industrially for a variety of purposes, including packing, insulation and transportation. It’s also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.
Cooking With Aluminum Foil May Increase the Aluminum Content of Foods
Most of your aluminum intake comes from food.
However, studies show that aluminum foil, cooking utensils and containers can leach aluminum into your food.
This means that cooking with Household Aluminum Foil may increase the aluminum content of your diet. The amount of aluminum that passes into your food when cooking with aluminum foil is affected by a number of things, such as:
Temperature: Cooking at higher temperatures
Foods: Cooking with acidic foods, such as tomatoes, cabbage and rhubarb
Certain ingredients: Using salts and spices in your cooking
However, the amount that permeates your food when cooking can vary.
For example, one study found that cooking red meat in aluminum foil could increase its aluminum content by between 89% and 378%.
Such studies have caused concern that the regular use of aluminum foil in cooking could be harmful to your health. However, there is currently no strong evidence linking the use of aluminum foil with an increased risk of disease.
What Is Blister Packaging?
PVC Blister packaging is widely used across the pharmaceutical industry as a unit-dose packaging solution that helps people take the correct amount of medication at the right time.
Blister packaging is made using several types of rugged polymers, including:
Polyethylene terephthalate (PET)
Polyvinyl chloride (PVC)
Polyvinylidene chloride (PVDC)
Polychlorotrifluoroethylene (PCTFE)
Cyclic olefin polymers (COP)
Blister packaging is manufactured from a plastic sheet that is thermoformed to create cups or blisters that hold a product in place. The packaging typically has a paperboard backing or a lidding seal of aluminum foil or plastic film.
Blister packs provide a safe, secure way to ship medicines and small consumer items, offering additional protection when goods are transported inside custom cardboard boxes. Each type of material used to create blister packaging offers something different.
Obviously, size is an important consideration when buying Laminated Composite Film. You will need to know how wide your machine is and then buy film that’s compatible with that width. You will also need to think about the size of the document you plan on laminating. For example, if you’re laminating letter-sized items, you can use film that’s 12 inches or wider and trim away the excess. The length of the roll isn’t as important as the width, so you don’t need to worry too much about that. Just make sure the roll isn’t too long for your laminator.
Thickness is an important factor when choosing laminating film. If you read your machine’s instructions, it will tell you what thickness the laminator can handle, whether it’s something on the lower end of the scale such as 1.5 mil film or something thicker, like 10 mil laminate. The higher the mil number, the more rigid your laminated document will be. Keep in mind that a lot of school laminators can only handle the thinner films, such as 1.5 and 3.0 mil film.
