Advantages of Plastic Preservation Box

Durability and strength
One of the primary advantages of plastic preservation box is its durability and strength. Plastic containers can withstand high levels of stress and pressure, making them ideal for use in food storage and transport. Unlike glass or metal containers, plastic is not prone to breakage or shattering, making it a safer and more convenient option.

Lightweight and easy to transport
Plastic preservation box is also lightweight and easy to transport, which is especially beneficial for those who need to carry their food with them. Plastic containers are lighter than their glass or metal counterparts, making them easier to handle and transport.

Airtight and moisture-resistant
Another advantage of plastic preservation box is its airtight and moisture-resistant properties. plastic containers can effectively seal in the freshness of food, keeping it free from moisture, air, and other contaminants. This makes plastic packaging an ideal option for perishable food items like fruits, vegetables, and dairy products.

4 Plastics That Are Best to Use for Food Storage Containers

When it comes to food storage containers, plastic is one of the most popular materials to use. There are many different reasons why people tend to opt for a plastic container box for food. For one, plastic containers are very durable. They do not crack or break easily even when you toss or push them. They are design to endure tough situations, so they usually last long.

PET

Polyethylene terephthalate or PET is a chemically stable polyester that is used in manufacturing many different products. It is a clear, lightweight, and strong plastic that is excellent for storing food and water even for the long term. What is better about PET as a food storage solution is that it is also 100% recyclable. Therefore, it is a good option if you are conscious about the environment.

PET containers have incredible oxygen barrier qualities and can be utilised with oxygen absorbers for storing bulk dry goods. The sealed containers’ low oxygen content protects the stored food from insects and helps maintain product quality. PET containers are best suitable for products that are rotated regularly, while still delivering numerous years of storage capability.

Here are the food items and beverages commonly stored in PET containers:
Juices
Soft drinks
Pickles
Peanut butter
Salad dressing

LDPE

Low density polyethylene (LDPE) is a soft, lightweight, and flexible thermoplastic material that is noted for its toughness, low temperature flexibility, and corrosion resistance. It is considered less toxic compared to the other types of plastic and is relatively safe to use for storing food and water. Unlike PET, the products made with LDPE plastic are usually reusable but not always recyclable.

Here are the kinds of food containers commonly made with LDPE:
Bread packaging
Squeezable bottles for honey and mustard
Frozen food bags

HDPE

High density polyethylene (HDPE) is a thermoplastic made from ethane and is considered as one of the most versatile plastic materials out there. It is weather-resistant, impact-resistant, and long lasting. In comparison to other plastics, HDPE has proven itself at delivering a strong surface durability. Like PET, HDPE is also extremely easy to recycle, so it is another great option for the eco-conscious folks.

Here are the food or beverage containers commonly made with HDPE:
Milk containers
Juice containers
Chocolate syrup containers
Vinegar bottles
Squeeze butter bottles

Rectangular Food Storage Containers With Lids

Polypropylene (PP) is a widely used thermoplastic made from the combination of propylene monomers. It is lightweight and tough but can still be flexible as well. Unlike many other kinds of plastic, PP has a high heat resistance, so the possibility of chemicals leaching into PP containers is low. As such, it serves as an effective barrier against chemicals, moisture, and grease. PP is a great choice for food storage containers because it can hold up well in hot environments.

Here are the food or beverage storage items commonly manufactured with the use of PP:
Deli meat containers
Potato chip bags
Yogurt containers
Margarine tubs
Plastic bottle tops
Medicine bottles

Tips For Choosing Plastic Preservation Box

Choose full transparent or milky white as much as possible: most of the cheap plastic preservation boxes are made of cheap raw materials, because their raw materials are not pure enough, so if they are made translucent or milky white, the impurities in the raw materials will be very eye-catching, and the color of the finished products will become very poor. Therefore, cheap plastic preservation boxes usually add toner to the raw material to make the shell colorful, so that the impurities in the raw material can be "mixed up".

You can choose according to the smell: if there is a choking smell, it is a fake and shoddy plastic preservation box. Since plastic preservation boxes often store clothes and other everyday items, they must be chosen carefully. First of all, if the material is PP, see if there is a recycling mark on the bottom of the preservation box.

Care about the quality, the thickness of the materials, and the clarity of the fully transparent preservation box: the colorful preservation box depends on the purity of the tone, and it is difficult to make products with high tone contrast from fake and inferior raw materials. Keep an eye on the specs.

The specifications of the preservation box should be designed to be conducive to preservation and taking and placing without occupying too much indoor space in the house: the preservation box is mainly used as a preservation cabinet application for daily assistance, and its primary function is to store and organize some objects with a small volume.

How to Clean Plastic Preservation Box

The Production Procedure of Plastic Preservation Box

When we select PP, PET and PVC plastic preservation box materials for production, the thickness of PVC and pet is suggested to be 0.10-0.55mm, and the thickness of PP can reach 0.75mm. The thickness of plastic preservation box materials should not be too thick, so as to facilitate the next step of die cutting. Too thick materials will lead to too hard mounted plastic box, It's not beautiful

Plastic preservation box printing generally does not print on the outside of plastic box, only through silk printing. Plastic box is usually external packaging, which requires high printing technology. If printing on the outside of plastic box, it is easy to cause color difference, ink dot, ink drop and other conditions that affect the appearance of packaging. Experienced manufacturers will not choose to print on the outside of plastic box.

The most important process of plastic preservation box production is die-cutting (beer). The knife mold used to cut the film in advance is placed on the die-cutting machine to cut the film, so as to prevent unnecessary damage to the later process.

Precautions When Using Plastic Preservation Box

Utilise food-grade plastic containers
A food-grade plastic container is basically one that does not transmit non-food chemicals into food. According to food safety experts, the use of non-food-grade plastic containers increases the chances of contamination in food. As such, it is necessary to always use food-grade plastic containers when storing food. Plastic containers should follow specific regulations to ensure that they are safe for food.

Freeze food only in plastic containers intended for the freezer
Similarly, if your food is intended to be placed inside the freezer, you should put it in a container that has a freezer-safe label. Plastics should only be placed in the freezer if they have this label. Other disposable containers, such as milk or ice cream cartons, must be avoided for freezer use. As much as possible, you should only use containers in the freezer that are leak-proof, easy to seal, and moisture-vapour resistant.

Wash plastic food containers by hand
Although certain plastics are safe to be put into the dishwasher, it is usually recommended to wash plastic food containers by hand. In doing so, you can ensure that those grooves around the container’s openings are clean so that no pathogen contaminates other food.

Try not to put microwave heating
Ordinary plastic crisper can only withstand the maximum temperature of 120℃, and it is easy to deform when heated in the microwave oven. It is best to use the special microwave oven box to heat, especially the food with more oil and sugar. When putting into the microwave oven, the lid must be loosened to engage the device before use. If used with the lid locked, the crisper can become deformed or burst due to pressure. When used in the microwave oven, if there is a lot of oil and sugar in the food, the temperature will rise rapidly, which will make the crisper deformation.

Don't rush to open it
Take the crisper out of the freezer. Don't open it right away. Let it sit at room temperature for a minute or two before opening it.

Can't you put all kinds of food
Fizzy or fermented foods, as well as carbonated beverages, can make the crisper less airtight or lose its seal, so try not to put them in the crisper. This is also true of foods that are too hot and are best cooled before being added.

Don't leave it too long
Even if you put it in the crisper and then put it in the refrigerator, it is not everything. The length of time that food will be kept varies, so it is better to eat it as soon as possible rather than relying solely on the sealing ability of the crisper.

Do not rely too much on the preservation function
Different foods can be stored for different periods of time. Do not rely solely on the sealing ability of the crisper.

FAQ

Q: What are plastic storage boxes called?

A: Storage bins are made of plastic and come with lids to protect your items from falling out during a move. They're also easy to stack and have handles for conveniently transporting your items from one place to another. They come in different sizes and are more durable compared to cardboard storage boxes.

Q: Are plastic storage boxes safe?

A: In general, the safest choices for food use are numbers 1, 2, 4 and 5. The American Academy of Pediatrics recommends avoiding plastic containers with codes 3, 6 and 7. Plastic number 3 contains vinyl or polyvinyl chloride (PVC), 6 has polystyrene and 7 can contain various plastics, such as Bisphenol A (BPA).

Q: Which plastic Cannot be processed again and again?

A: The plastics that cannot be remoulded or reshaped on heating are called thermosetting plastics/ thermosets. Few examples of thermosets are bakelite, melamine, polyurethane, polyester, etc.

Q: What plastics Cannot be reused?

A: Examples of non-recyclable plastics include bioplastics, composite plastic, plastic-coated wrapping paper and polycarbonate. Well known non-recyclable plastics include cling film and blister packaging.

Q: How do I know if my plastic is freezer safe?

A: If you don't see the snowflake symbol, avoid putting your new containers in the freezer. Extreme temperatures can deteriorate plastic, and if containers aren't food safe, this can cause chemicals to spread to food when the containers are taken out of the freezer.

Q: Which plastic is safe for hot food?

A: Polypropylene is FDA-approved for food contact and also has a high heat tolerance. It is known to be a safer alternative to most other plastics. It can be used to heat beverages or foods without leaching.

Q: Is reusing plastic containers safe?

A: Generally speaking, you'll want to throw them away after a few months to reduce the risk of bacterial build-up or leaching plastic. The end result (of reusing them) is an increased intake of compounds that disrupt the endocrine system over time.

Q: Can you put plastic boxes in the freezer?

A: Rigid containers and flexible bags or wrapping are two general types of packaging materials that are safe for freezing. Rigid containers made of plastic or glass are suitable for all packs and are especially good for liquid packs. Straight sides on rigid containers make the frozen food much easier to remove.

Q: What are the safety precautions for plastic preservation box?

A: Plastic food containers must follow specific regulations to make sure they are safe for food. Use single-use containers once. Plastics designed for single use should be used only once. Plastic breaks down over time, and some items are not designed to withstand heating and cooling.

Q: How is plastic preservation box made?

A: Two main types of processes exist: One-step injection molding – the melted polymer is injected into the final shape of the container in a cold mold, it's then released. Two-step injection molding – the first step in the injection of melted plastic in a mold, resulting in the creation of a preform.
