PET Plastic Hinged Lid Containers
Overview
PET plastic hinged lid container mainly consists of two parts: the container body and the lid connected by a hinge.
Among them, the container is used to store items, with various shapes include square, round, etc. The lid is connected to the main body by a hinge and can be flexibly rotated relative to the container body, making it easy to open and close. The advantage of this structure is that it can effectively protect the internal items and prevent them from leaking, while being convenient for users to operate.
Besides, it's made of PET, a plastic that is easily recyclable and renewable. With transparent appearance, it is often used to make food and beverage containers, textiles and packaging.
What are the Advantages of PET Plastic Hinged Lid Containers?
Lightweight
PET Plastic Hinged Lid Containers are lightweight because PET has a relatively low density. The lighter weight helps us reduce costs in the process of transporting large quantities of packaging. Also, they are easier to carry for consumers.
Drop-Resistant
Compared with materials such as glass, food containers made of PET are not easy to break when impacted by external forces. Even if the container is stacked and squeezed or accidentally dropped, it can remain intact. This is because the PET molecular chain contains a benzene ring structure. Benzene rings are like steel beams in buildings, which can provide support for the entire molecular structure.
Highly Sealed
These hinged lid containers adopt a snap-on opening design, with a concave-convex structure on the edges of the lid and the box body. This design is similar to a mortise and tenon structure. When the lid is closed, the convex part is embedded in the groove to form a relative sealing state. They prevent food from falling out and reduce the flow of air and liquid in and out, slowing down oxidation.
Highly Transparent
PET is a material with good optical properties. Its transparency is extremely high, reaching more than 90%, comparable to glass. Therefore, the food packaging box made of it can clearly show the food inside, including its appearance, color, and texture.
Uses of PET Plastic Hinged Lid Containers
Hinged containers are widely used in the foodservice industry because of their versatility. Here are some common uses for hinged containers:
Restaurant Takeaway
PET Plastic Hinged Lid Containers are widely used in takeaway business of various restaurants. They are available in different capacities and can hold enough dishes for one or more people. You can use them to pack various dishes, soups and fast food.
Fruit Shop
In fruit shops, hinged lid containers are often used to pack fresh cut fruits, such as cut watermelon cubes, cantaloupe cubes, strawberries, etc. The highly transparent surface is conducive to showing the freshness of the fruit and attracting customers to buy. The relatively sealed structure prevents the fruit juice from flowing out and is convenient for customers to carry.
Household Use
In the family, we always need to prepare a large portion of dinner, and sometimes we leave some dishes but don’t want to waste them. At this time, we can use these hinged lid containers to store leftovers. They support storage in the freezer and heating in the microwave, and ensure that BPA is not released. This is important for the health of your family.
Non-Hinged vs Hinged Containers for Takeaway Foods
Non-Hinged Containers
Advantages:
● Its structure is simple and there is no dead corner for cleaning.
● Its sealing performance is worse than that of hinged lid containers. If you need to open and close it frequently, please check whether the edges are fitted.
● There are no movable hinge parts, and the connection between the lid and the container is not easy to wear.
Disadvantages:
● The lid is separated from the container and should be placed separately when stored. This may waste time in packing when there is a large flow of people.
● The connection between lid and the body may be deformed after being hit, squeezed.
● The lid is separated from the container, and the matching degree should be considered in the design.
Hinged Containers
Advantages:
● Users can open or close the container simply by turning the hinge, and the lid will not be lost.
● Hinged containers have good sealing properties. When closed, the lid fits tightly with the container to prevent leakage of internal items.
● The hinge connection is relatively strong and can withstand slight external impact and pulling.
● Some hinged containers can be designed to be foldable or nested, making them easy to stack and store.
Disadvantages:
● If the hinge is of poor quality or the design is unreasonable, problems such as jamming may occur.
● Due to the limitations of the hinge structure, the shape and size of hinged containers are usually relatively fixed. They may not be as convenient as non-hinge containers when stacked for storage.
● The presence of the hinge structure may increase the manufacturing cost of the container.
How to Choose PET Plastic Hinged Lid Containers
Material
If you want to use PET Plastic Hinged Lid Containers for food packaging, first make sure it is BPA free. Secondly, PET containers used for food packaging must meet relevant food safety standards. You should check whether it has a food-grade certification mark. The easiest way is to pay attention to the "recycling" code on the bottom of most containers: items marked with 1, 2, 4 and 5 are most suitable for storing food.
Capacity
If it is used for home storage of leftovers, we may need containers of different sizes. For example, 200-300 ml is used for a small amount of side dishes, 1-2 liters is used for soups, etc. For commercial use, such as the takeaway industry, consider the amount of dishes and the cost of the container. Generally, the capacity of a single-serving dish container is about 500-800 ml.
Sealing
Check the sealing structure of the container, which can help you prevent soup from spilling during subsequent use. The hinged lid container is relatively sealed, which is achieved by the snap-on design of the lid and the body. In addition, we can put a small amount of water into the container, close the lid, invert or shake the container, and observe whether there is liquid leakage to test its sealing.
Appearance Quality
When choosing, pay attention to the transparency of the container and surface scratches and bubbles. High-transparency containers often show the contents better. In addition, consider the shape, color and surface treatment of the container. Some PET containers can use frosting, silk-screening and other processes to add value to your products.
Durability
If your food needs to be transported over long distances, please choose a container with higher strength, such as a thicker container wall. Secondly, check the quality of the hinge because it needs to be opened and closed frequently to see if it is stuck, loose or easy to break.
Cost and Environmental Protection
When buying in bulk, compare the price and quality of different suppliers and choose the food packaging that best suits you. And remember that PET materials are recyclable. Some PET containers are also made of partially recycled PET materials, which is also a good choice for environmentally friendly containers.
