Shrink wrap food bags are a convenient way to store and transport meals, keeping them fresh for a longer period. They come in different sizes and are suitable for wrapping individual portions or large quantities of food.
Shrink wrap food bags are made from a thin, flexible plastic material that can be heat-sealed to form a tight seal around the food. This prevents moisture and air from entering the bag, which can cause food to spoil quickly.
Using shrink wrap food bags can help reduce food waste by keeping food fresh for a longer time. According to some studies, shrink wrap food bags can extend the shelf life of food by up to 50%.
What Are Bags?
Shrink wrap bags are made of polyethylene terephthalate (PET) or polyvinyl chloride (PVC). They're used to package products that need protection from the environment and will be heated in a shrink tunnel.
Shrink wrap bags are used to protect products from moisture, dust, and other contaminants. This prevents damage during shipping.
The film is placed around the product and then heat is applied, causing the film to shrink and form a tight seal around the product. This creates a secure and airtight package.
Shrink wrap bags are used to protect, package, and market a variety of products, including food items like candy, nuts, and potato chips. Non-food items like toys, hardware, and pharmaceuticals also use these bags.
Benefits and Uses
Shrink wrap bags are an excellent way to store food, providing a tight seal around whatever you're storing.
They're made of a thin plastic film that shrinks when heated, keeping food fresh and protected against pests.
Make sure the food is completely dry before sealing it in the bag.
Never heat the bag more than necessary, as too much heat will cause the plastic to melt and could potentially release toxins into your food.

Benefits of Bags
Shrink wrap bags are a great way to store food, keeping it fresh and protected against pests.
Shrink wrap bags are made of a thin plastic film that shrinks when heated, providing a tight seal around the food.
This makes them ideal for storing food that needs to be kept dry, like baked goods or snacks.
To use shrink wrap bags effectively, make sure the food is completely dry before sealing it in the bag.
Heating the bag more than necessary can cause the plastic to melt and potentially release toxins into the food.
Labeling the contents of each bag is also crucial, so you know what's inside and can easily identify it later.
How to Use Bags
Shrink film bags are a great way to store food, especially if you want to keep it fresh and avoid freezer burn.
To use them, start by putting the food you want to store in the bag, then seal it up tight. Remove any excess air from the bag before you shrink it, since this will help prevent freezer burn.
Putting the bag in boiling water for a minute or two until the film shrinks tightly around the food is the next step. Once the film has shrunk, your food will be securely sealed and well-protected from the elements.
Types and Options

Shrink wrap food bags come in three main types: PVC, Polyethylene, and Polypropylene. Each type has its own unique characteristics that make it suitable for different products.
PVC shrink film bags are the most common type and offer good protection for your products. They're made from durable PVC plastic.
Polyethylene shrink film bags are thinner than PVC bags but offer excellent clarity and durability. This makes them a great option for food products that need to be visible.
Polypropylene shrink film bags are the thinnest and most flexible type of bag, making them perfect for delicate items.
Types of Bags Available
There are three main types of shrink film bags: PVC, Polyethylene, and Polypropylene.
PVC shrink film bags are the most common type and offer good protection for your products.
Polyethylene shrink film bags are thinner than PVC bags but offer excellent clarity and durability.
Polypropylene shrink film bags are the thinnest and most flexible type of bag, making them perfect for delicate items.
PVC is the cheapest option but it's also less durable and not as environmentally friendly as the other two options.
Polyolefin bags are actually mentioned in another section, but Polypropylene bags are a good compromise between durability and price.

They're crafted from premium Polyolefin, which is a non-brittle, flexible, and FDA-approved material. This makes them durable, with minimal odor and crystal-clear clarity.
These bags are generously sized, making them versatile and ideal for a variety of packaging needs.
Heat Bags
Heat bags are a popular choice for food storage, especially for leftovers. They're often used in conjunction with shrink wrap bags to keep food fresh for a longer period.
Heat bags are designed to retain heat, keeping food warm for several hours. This is especially useful for families who have busy schedules and need to keep meals warm for a longer time.
Some heat bags are made with a special type of insulation that helps to retain heat. This insulation can be made from materials like foam or fiberglass.
Using heat bags with shrink wrap bags can help to keep food warm for up to 4 hours. This is a significant improvement over not using any heat retention methods.
Heat bags can be reused multiple times, making them a cost-effective option for food storage.
Frequently Asked Questions
Are shrink wrap bags food safe?
Yes, crosslinked polyolefin shrink film is a food-safe option, sterilized through irradiation in production. This ensures the film meets food safety standards and is suitable for packaging food products.
What is the difference between shrink bags and vacuum bags?
The main difference between shrink bags and vacuum bags is that shrink bags don't create a true vacuum seal, while vacuum bags do. This distinction affects the level of protection and preservation for the contents inside.
What temperature do you shrink wrap bags?
For shrink wrapping with our polyethylene material, use a heat gun temperature between 160-350°F to ensure a tight seal. This temperature range prevents the film from sagging or coming loose.
