Food plastic wrap, also known as cling film, food wrap, and saran wrap, is a thin plastic film commonly used for sealing and securing food items in containers to keep fresh.
Plastic wrap, cling film, Saran wrap, cling wrap, Glad wrap or food wrap is a thin plastic film typically used for sealing food items in containers to keep them fresh over a longer period of time.
Clingfilm is invaluable for covering dishes of leftovers or wrapping awkwardly shaped food items.
Keeping food fresh: Whether you have leftovers or need to keep newly-prepared products fresh, cling film is the answer.
The three main wraps used in shrink packaging material for protecting and securing products for the retail and shipping environments are polyvinyl chloride (PVC), polyethylene (PE), and polyolefin (POF).
A – PVC is the film of choice for the majority of professional caterers as it has the best cling properties and is suitable for 95% of all food use. PE film lacks the cling properties of PVC cling film and is suitable for wrapping high fat foods such as lard, butter, cheese and fish.
The bottom line: While there is no evidence to suggest that the newer, reformulated plastic wraps leach harmful compounds into food, keeping the wrap at least 1 inch from food surfaces will eliminate any potential risk.
And even when plastic wrap is recycled, it's costlier than using virgin materials. When it ends up in landfills or incinerators, both PVC and PVDC can release a highly toxic chemical called dioxin, says the World Health Organization.
Glad ClingWrap contains no plasticizer, and is BPA free and microwave safe.
Glass Jars
For smaller items, repurposed glass jars work perfectly. They have the see-through nature of plastic wrap and can be popped in the dishwasher after being used. Whether you buy mason jars or save up old jam jars, pickle jars, etc., this option is super affordable.
Plastic wrap is hazardous in itself, and it contributes to the scourge of plastic pollution. It contains either PVC (polyvinylidene chloride) or low-density polyethylene, neither of which are harmless. It is difficult to recycle and can leach chemicals into your food if microwaved.
Polyvinylidene chloride, or PDVC, is the polymer in plastic wrap that makes it stick to itself so well.
(fuːd ræp ) a thin polythene material that clings closely to any surface around which it is placed, used for wrapping food. Cover tightly with plastic food wrap and refrigerate overnight.
The USDA says plastic wrap is actually safe to use in the microwave, as long as it's labeled microwave-safe. More importantly, they recommend that the plastic wrap not touch the actual food.
Food wrappers come in a variety of types and sizes. Food packaging can be made of polypropylene (PP), polystyrene (PS), or polyethylene (PE).
Plastics that are numbered 2 and 4 are less toxic than other plastics, given that they are composed of high-density and low- density polyethylene, respectively. Plastic wraps with the number 5 are composed of polypropylene, and are also generally considered safer to use.
The plastic wrap keeps foods fresh by protecting them from the air which can expedite spoiling and oxidation, preventing unwanted drying, and preventing undesirable moisture absorption. They can also help keep food odors contained.
While both materials have their advantages, there are some key differences between them. Here are some of the differences between foil wrapping and plastic wrapping solutions: Permeability: Foil is generally more impermeable than plastic, meaning that it can better protect the contents from air, moisture, and odours.
Storage containers and wax wraps are your best bet. Simply pop your sandwich or leftovers in a container to take to work, or use wax wraps to keep products such as cake and cheese fresh. The most common type of wax wrap is beeswax.
Plastic wrap in the United States is made of polyvinyl chloride or PVC and contains a “plasticizer” called di(2-ethylhexyl)adipateor DEHA. DEHA is not a phthalate but is chemically very similar to the phthalate DEHP, which is di(2-ethylhexyl)phthalate).
The researchers have tested the film using two forms of antibiotic resistant bacteria— methicillin resistant Staphylococcus aureus (MRSA) and pseudomonas. Using an electron microscope, they reported that virtually no bacteria could transfer to the surface.
The study found that one of the cling film brands had a very high concentration of DEHA, which may result in adverse health effects and carcinogenic risks. Cancer risks resulting from exposure to DEHA equated to about five in 1000 people, which is 50 times higher than the acceptable cancer risk, said Prof de Jager.
Our advice: Use ceramic or glass cookware for microwaving, and instead of plastic wrap, cover food with an overturned microwave-safe bowl or plate. In the test kitchen, we have found that this retains moisture just as well as plastic wrap, with zero risk.
