Square Aluminum Foil Pan with lid 8 x 8 inchesSquare Aluminum Foil Pan are used in caterings and even daily life nowadays. The 8×8 inch Square Aluminum Foil Pan has some advantages, so Square Aluminum Foil Pan also takes up an important position among many types of lunch box. This can be observed from, restaurant takeout, family gatherings, and food processing companies.
8 inch x 8 inch square aluminum foil lunch box production process
As a special material with a wide range of applications, the production of 8x8 square aluminum foil lunch box can be summarized as several key links, each link will have an important impact on the quality and performance of the product.
♦Raw material preparation
The production of 8x8 inch Aluminum Foil Pan with Cover is mainly made of aluminum foil. Aluminum foil is a kind of hot stamping material, it is made with metal aluminum being rolled directly into thin sheets. Aluminum, the key raw material of this product, has many advantages like light weight, good ductility and strong barrier properties. Aluminum foil is under strict quality control by manufacturers, including purity and thickness. Importantly: the purity of aluminium foil for lunch box should be high, because if the raw material is not pure, it will burn and volatilize after heating, leading to certain health problems. Built with only 0.01mm 0.05mm thickness according to lunch box design requirement & actual use scenario. Apart from the aluminum foil itself, the assembly and sealing of the lunch box may also involve some auxiliary materials or adhesives.
♦Mold design and manufacturing
The mold is an essential tool to determine the shape and size of the Aluminum Foil Pan with Cover. Precision for mold for 8 inch aluminum foil pan The designer will first use professional CAD (Computer Aided Design) software and create a 3D model that meets the lunch box specifications. When modeling for the lunch box, consider the wall thickness, corner rounding, and how far the shoulder for reinforcing ribs are, etc., to ensure that the lunch box has enough strength and stability. The mold is produced by processing the equipment in the mold after the design is completed by computer numerical control (CNC). The error is controlled in a very small range, which can effectively ensure the high precision of the mold and ensure the produced breakfast box size accurate and consistent.
♦Stamping
Apply of 8 inch aluminum foil pan(8×8 inch square aluminium foil lunch box) Stamping is one of the basic links in the aluminum foil lunch box production. The punching machine punches the aluminum foil according to the shape and size of the mold. In the punching process, the strong pressure will cause the aluminum foil to deform in a short time, forming the basic shape of the lunch box. During this process, the control of the punching pressure, speed and temperature requires strict control.
♦Trimming and deburring
There might be some rough areas and burrs on the edges of processed lunch boxes. Such problems can compromise the aesthetics of the lunch box, but also cause damage to the user. Hence trimming and deburring are necessary.
♦Cleaning and disinfection
Therefore, in order to ensure the hygiene and safety of the lunch box, the lunch box also needs to be cleaned and disinfected in the production process. Usually, the cleaning can use professional cleaning agents and cleaning equipment, which can be very clean for lunch box surface grease, dust and impurity removal. A lunch box is subjected to high temperature disinfection or chemical disinfection after cleaning.
♦Quality inspection
8 * 8 Square Aluminum Foil Lunch Box process quality inspection throughout. In the procurement of raw materials, for example, the aluminum foil will be subjected to quality inspection, purity inspection, thickness inspection, tensile strength inspection, etc. The production will be randomly inspected and accepted during the inspection process of each production link, such as the lunch box size inspection and appearance inspection after the stamping link. With the advent of RFID technology, we can reduce human error to inspect if the products are correctly sealed and avoid contamination of the product as we know before reaching the RFID technology during the quality inspection of the product before packaging the complete inspection done with respect to sealing inspection, compressive strength inspection, hygiene index inspection, etc.
♦Packaging and warehousing
In order for the quality inspection to come out to an imported 8x8-inch square aluminum foil lunch box, it will enter the packaging link. Generally, there are 2 methods of packaging — single packaging and batch packaging. Single packaging is the most widely used method, which is to seal each lunch box with plastic film or paper box to prevent the lunch box from being contaminated and damaged during transportation and storage. This refers to putting many lunch boxes into a bulk carton or plastic box for easy transport and storage. The product name, specifications, production date, shelf life, manufacturer and other information are printed on the packaging during the packaging process. These packed lunch box will be sent to warehouse for storage and waiting for the shipment. To avoid damage to the quality of the lunch boxes, the warehouse atmosphere must be maintained dry and ventilated.
Types of material for 8x8 inch square aluminum foil lunch box lid
The 8x8 inch square aluminum foil lunch box lid material types are rich and varied, the different materials have different characteristics and applicable scenarios.
♦Aluminum foil material
The aluminum foil cover is the same material as the main body of the lunch box, has good barrier properties, moisture-proof ability and high temperature resistance. The aluminum foil lid can isolation moisture and grease in the food and can prevent food from being evaporated, making the food more fresh and delicious. At the same time, aluminum foil has a certain light-shielding property, which can prevent the food from being affected light and deteriorating. The aluminum foil lid can be sealed directly with the lunch box, with good sealing performance, can effectively prevent food leakage. Also, the aluminum foil material has the environment protection requirements and recycling properties.
♦Plastic material
These types are more common plastic lids. The most common plastic materials are polypropylene (PP), polyethylene (PE), etc. U: The PP lid has high heat resistance and is not easy to deform under certain temperature. PE lid with good flexibility and low temperature resistance of the PE lid are suitable for individual foods that need to be refrigerated or frozen. The disadvantages of plastic lids are a wide variety of color and pattern designs, low production cost and simple production process. But the barrier properties of plastic materials are relatively poor, and are not as good as aluminum foil materials in preventing the moisture and grease evaporation of food.
♦Paper material
In recent years, paper lids have attracted more and more attention because of environmentally friendly, degradable. Usually paper lids are made of kraft paper, white cardboard and other materials. After special waterproof and oil-proof treatment, can meet the lunch box packaging requirements. The advantage of paper cover is that it has good environmental performance and no pollution to the environment. On the other hand, a variety of patterns, text can be printed on paper materials, has a good publicity ornamental effect. But paper lid moisture resistance and sealing performance is relatively poor, when using, and try to avoid moisture and collision.
♦Composite materials
To take advantage of 8x8 inch square aluminum foil lunch box lids, some manufacturers will also use composite materials. So for instance, there is aluminum foil compounded with plastic, or paper materials compounded with plastic. It has the flexibility and cost advantage of plastic, or it has this composite lid with both the barrier and moisture resistant properties of aluminum foil; or it has both the environment of paper materials and the sealing property of plastic.
Because of its own performance and characteristics, 8X8inch square aluminum foil lunch box can be widely used in various fields.
Catering industry
