This transparent plastic lid + black opaque plastic-like style should be the most common take-out box ~ everything from the design ... Well, skip it, let's look directly at the manufacturing!
Factory-made plastic products of all kinds of small plastic particles, can be molten and then shaped into the desired shape, such as the take-out box in this article, we are first to make plastic sheet, and then thermoformed.
The picture below looks like a flat plastic sheet being heated and then blistered into shape afterwards, look at this one like a silver plate is the metal mold. The production process does not look very simple and brutal ...
After forming the lid of the take-out box will be heat-embossed with production information.
After die-cutting, cut off the excess parts, and then a stack, into a dozen take-out box lids are piled together to be launched.
After manual sampling and disinfection, a large package to make a seal, factory!
Is not suddenly feel the production of plastic take-out box lid some familiar? Because similar plastic containers, are more or less the same production process, so the black bottom of the take-out box skipped it ~
Nowadays, when you buy a box lunch sold on the high-speed train or buy fast food at the station, you buy a single-sided sealed box lunch, using plastic film instead of the transparent lid of the fast food box. The whole sealing process is exactly the same as the sealing film seen in the milk tea store... The complete plastic film packaging is not only sealed and spill-proof, but also makes people feel that the food packaging out of the field so that no one has moved, very safe, some similar to the role of the "anti-theft ring of the bottle cap".
Speaking of which, ten years ago when the common use of disposable foam fast food boxes, and now has been completely replaced by the black bottom + transparent cover of the plastic fast food boxes. The raw material of this kind of foam take-out box is foam plastic, and firstly, the rolls of plates are unrolled and sent to the assembly line.
First, the shape of the lunch box is hot pressed on the left side, and then transported to the right side for cutting.
After cutting, the lunch boxes are pressed down by the machine to the bottom of the assembly line for collection. Come to see the details of the piles, rows and rows are pushed out.
After that, they are sent to manual hands for random quality check.
If you order any barbecue or stew, the store may use aluminum foil packaging to send you the food, the advantage is that if you get your hands on the dish has been cold, you can also put the take-out box in the oven, stove fire heating. (Remember not to use the microwave oven!)
Aluminum foil sheets go in, a vigorous out of the miracle of stamping ...
Look at a mold of the concave and convex model to write, really did not find the animation effect picture ... Look at the static picture.
The pattern is made directly on the mold, a squeeze up and down, the aluminum foil is made to look like a fast food box.
After the punch was a stream of air collapsed, go you, let the take-out box fly for a while ...
Finally they are manually collected in one place!
