Plastic wrap types and their uses
Plastic wrap is a general term used to describe many different materials. The most common type of plastic wrap is the thin plastic film used to seal food in containers to keep it fresh. This type of plastic wrap is commonly known as cling film, food wrap, or Saran wrap. It is typically sold on rolls in boxes with a cutting edge.
The original plastic wrap was made from polyvinyl chloride (PVC), which is still the most common component globally. PVC has low permeability to water vapour and oxygen, helping to preserve the freshness of food. However, there are concerns about the environmental impact of PVC, as well as the transfer of plasticizers from PVC into food. As a result, some brands, such as Saran Wrap, have switched to using low-density polyethylene (LDPE) due to environmental concerns. LDPE is a cheaper alternative to PVC but is less adhesive. This can be remedied by adding linear low-density polyethylene (LLDPE), which also increases the film's tensile strength.
Another type of plastic wrap used in the food industry is polyvinylidene chloride (PVdC). PVdC was the original plastic wrap invented in 1933 but is now less commonly used due to environmental concerns. It is still used by some brands and provides excellent protection for food from chemicals, gases, moisture, and light.
In addition to food packaging, plastic wrap is also used in the medical and pharmaceutical industries. For example, plastic wrap can be used as a first aid dressing for burns, and to wrap premature babies to prevent low temperature after birth.
Other types of plastic wrap include stretch wrap and shrink wrap. Stretch wrap is a stretchable plastic used to keep items tight, intact, and safe during transport. It is commonly used to wrap pallets and bulky items. Stretch wrap is recyclable, making it a more environmentally friendly option. Shrink wrap, on the other hand, requires heat to wrap around products and is more commonly used for retail products.

How to wrap containers tightly
Plastic wrap, also known as cling film, food wrap, or Saran wrap, is a thin plastic film used to seal and secure food items in containers. It is commonly sold in rolls with a cutting edge.
- Choose the right type of plastic wrap. Most consumer brands of plastic wrap are made from low-density polyethylene, which has reasonable stickiness. For a stickier option, look for products made from PVC, such as "meat film", which is commonly used in grocery stores.
- Consider the surface you are wrapping. Plastic wrap tends to stick better to ceramic and glass surfaces than to metal or wooden ones.
- Keep the plastic wrap taut as you cover the container. This will help prevent wrinkles and ensure a tight seal. You can use your forearm to smooth out the plastic wrap as you pull it over the container.
- When using a serrated cutter box, pull the plastic wrap towards you, keeping it taut, and tear it against the cutter.
- For an even tighter seal, try using a heat sealer. These are heated pads that you can place the wrapped container on for a few seconds to shrink the plastic and pull it taut.
- To prevent creamy items from spoiling, create an airtight layer by ensuring the plastic wrap touches the product directly.
- To prevent odours and extend shelf life, double bag strong-smelling items or place them in a plastic container after wrapping.
Remember to always research the brand of plastic wrap you are using to ensure it is safe for food preparation and does not contain harmful chemicals.

Safety concerns and alternatives
Plastic wrap is a general term used to describe many different materials, including industrial plastic wrap and food-grade plastic wrap. Food-grade plastic wraps, also known as cling film, food wrap, or Saran wrap, are commonly used for sealing and securing food items in containers to keep them fresh. However, the use of plastic wraps raises several safety concerns.
Plastic wraps, particularly those made from polyvinyl chloride (PVC), have been linked to health problems, earning it the nickname "the poison plastic." Studies have shown that PVC contains a plasticizer called di(2-ethylhexyl) adipate (DEHA), which can migrate from the plastic wrap into food, especially high-fat foods. DEHA has been found to cause liver tumors in mice and has been detected in various cheeses, meats, and poultry sold in grocery stores. As a result, many companies have switched to using alternative materials, such as low-density polyethylene (LDPE), which is considered safer but may not provide the same level of cling as PVC.
To address these safety concerns, it is recommended to avoid allowing plastic wrap to come into direct contact with food, especially when heating or dealing with high-fat foods. This is because plastics can break down over time and release trace amounts of microplastics and chemicals into the food, which can be harmful to human health. Single-use plastics, such as those used for bottled water, should never be reused as they can degrade and release harmful chemicals.
Instead of using plastic wraps, there are several reusable alternatives available, such as beeswax wraps, bowl covers, silicone food bags, and reusable food storage containers. Beeswax wraps, made from beeswax-infused cotton, can be moulded around food and bowls, creating a natural seal without leaving behind residues. Silicone lids and covers are also versatile and create a tight seal on bowls and dishes, making them a popular alternative for microwave use. Reusable sandwich wraps made from washable cotton or beeswax-infused fabric are another eco-friendly option for storing lunches and snacks on the go.
Additionally, simple household items such as plates, bowls, and glass lids from thrift stores can be used as food covers to replace plastic wraps. Banana leaves, which are waterproof, flexible, and compostable, have also gained popularity as a creative and natural alternative to plastic wraps, especially in grocery markets in Thailand. These alternatives not only reduce waste but also provide safer and more sustainable options for food storage.

The history of plastic wrap
Plastic wrap, also known as cling film, food wrap, and saran wrap, is a thin plastic film typically used for sealing food items in containers to keep them fresh. It is most commonly made out of PVC (Polyvinylidene Chloride) or PVDC, although in recent years, due to environmental concerns, LDPE (Low-Density Polyethylene) has become a more popular alternative.
Plastic wrap was accidentally invented in 1933 by Ralph Wiley, a lab worker at Dow Chemical. Wiley was attempting to wash out beakers used in developing a dry-cleaning product when he stumbled upon polyvinylidene chloride. The original formula was found to have excellent protective qualities, including the ability to form an effective barrier against oxygen, moisture, chemicals, and heat. This made it ideal for preserving food, as well as for industrial and consumer products.
In 1943, Wiley and his boss, John Reilly, completed the final work needed to introduce PVDC, and in 1949, Dow introduced Saran Wrap, a thin, clingy plastic wrap sold in rolls. The name "Saran" was derived from the names of Reilly's wife and daughter, Sarah and Ann. Saran Wrap quickly became a household staple, with over 200 million rolls sold in its first five years.
Today, plastic wrap is typically sold on rolls in boxes with a cutting edge, and it clings to many smooth surfaces without the need for adhesive. While it is commonly used for food storage, it also has a variety of other applications, such as securing pallets or protecting items during shipping.

Frequently asked questions
The best way to wrap containers in plastic is to first pull out the required amount of plastic wrap and place the container at the edge of the plastic wrap with the rest of the wrap behind the container. Then, grab the free end of the plastic wrap and stretch it over the container towards you, securing it under the container.
Some tips and tricks for wrapping containers in plastic include:
- Keeping the plastic wrap in the fridge as it sticks to room temperature or hot items better than it sticks to itself when cool.
- Sprinkling water on the counter before placing the container on the wrap, as the film will stay flat rather than wrinkling or bubbling.
- Using a heat sealer on the plastic to shrink the joint together and pull it taut.
- Using a product like Press'N Seal or Glad Press n' Seal for easier application.
Some things to avoid when wrapping containers in plastic include:
- Using plastic wrap with a serrated cutter bar, as it often results in a poor cut or the plastic sticking to itself.
- Using plastic wrap that contains harmful chemicals such as BPA, phthalates, PFAS, and diethylhexyl adipate (DEHA).
- Allowing plastic wrap to come into direct contact with food, especially when heating or if the food has a high fat content.
- Microwaving food in plastic containers, as it may release chemicals into the food.
Some alternatives to wrapping containers in plastic include using reusable containers, glass or ceramic containers, or aluminium foil. It is important to note that aluminium foil may not be suitable for highly acidic foods as they can eat away at the foil.
