In today’s society, people have increasing needs in all aspects of life. Everyone desires convenient products that offer outstanding benefits to save time and effort. This is why food storage bags have been created, becoming a trusted companion for housewives in preserving food for different periods of time. So why wait any longer? Let’s explore food storage bags and the popular types available on the market today.
1 What are food storage bags?
Food storage bags have become incredibly popular in recent times. Due to their lightweight nature, convenience, and affordable price, plastic food bags have almost replaced traditional boxes and paper, becoming an essential item in every household.
These bags are primarily made from polyethylene (PE) plastic with a small amount of polyvinyl chloride plastic. Polyethylene is a safe material that poses no harm to users. However, polyvinyl chloride, although not toxic, contains individual molecules that have the potential to cause cancer. As a result, many European countries have banned the production of food wrap films made from this material.
2 Types of food storage bags
Zip-lock food storage bags
Zip-lock food storage bags, also known as zipper bags, are not only used for storing food but also widely utilized for storing components and medical supplies. These bags have a zip closure that allows for easy opening and closing, keeping the food fresh and preventing external influences and odor contamination to other food items.
Zip-lock bags are made from high-quality, thick, colorless, odorless, waterproof plastic that can be reused multiple times, making them environmentally friendly. Due to these qualities, many housewives prefer zip-lock bags for food storage purposes.
Freezer food storage bags
Freezer bags are a special type of bag used to store frozen foods such as meat, fish, vegetables, etc. These bags preserve the freshness of the frozen items without freezing the water content.
Most freezer food storage bags have a versatile zip bag design that can be used to thaw food within or in a high-temperature environment. For safety reasons, the food should be stored at a continuous temperature of -17 degrees Celsius.
Vacuum-sealed food storage bags
Vacuum-sealed bags are primarily made from high-quality polyethylene that is thick, durable, and effectively prevents air penetration. These bags help preserve food without spoilage, keeping it fresh for a longer period of time.
In Vietnam’s hot and humid weather, fresh food items typically last 1-2 days. However, when stored in vacuum-sealed bags, their usage time can be extended to 1-2 months. To use vacuum-sealed bags for food storage, a special vacuum sealer is required to remove all air from the bag and ensure a secure seal.
Fully biodegradable food storage bags
Recently, fully biodegradable food storage bags have emerged in the market. These bags are designed to prevent air infiltration over an extended period, helping to protect food freshness and taste for a longer time.
- The bags are primarily made from natural starch derived from potatoes, corn, etc.
- They do not contain any harmful additives such as lead or cadmium, ensuring safety for humans.
- The bags decompose quickly within 6 months to 1-2 years in a natural burying environment, creating an environmentally friendly condition.
