How are disposable paper cups that can be seen everywhere in our lives made?

It is mainly made by machine and then batch production of paper and edible film that we often see.

The first point is that this crape myrtle is made of special materials, and the second point is that it is made of that special kind of paper and then pressed with a special mold, and the process of making it is very simple.

In life, the disposable paper cups we see everywhere are actually made of sawdust, so when using disposable paper cups, we must pay attention to reuse them and not waste them.

First of all, I will share with you the case of hand-made European-style toy chairs with disposable paper cups, and see how the paper cups have been transformed. Prepare a few paper cups, a few plastic cotton swabs, a pair of scissors, pins, and double-sided tape to start making; Divide the paper cup into quarters, leave the chair legs and cut the rest.

After cutting; Fold the chair legs and half the height will do; Then find a good distance, tear off one side of the double-sided tape, and leave the other side equidistant and stick it on the chair surface; Then stick it vertically, and then wrap each leg with double-sided tape in turn; Take a paper cup and cut out a piece of the back of the chair, hollow out to make the shape of the shape, and fix the back of the chair with double-sided tape, like a small chair without a bird! Finally, decorate the back of the chair with a cut strip of paper, find a good distance between the legs of the chair, put on a pin, and then cut off the two ends of the plastic cotton swab, leaving 2 small tubes strung on the pins to complete!

1. Sunflowers: a number of paper cups; Cut off the upper part from the middle and cut out the canine tooth shape with scissors; Use a pencil to roll the sharp corners of the paper cup outward; Two paper cups are stacked on top of each other. Chromatically.

2. Doll: straighten the edge of the cup; Tear the cup into even strips; Leave a part of the body that does not tear and wait for the spare paper cup doll; tear the remaining part into the body and limbs of the paper cup doll; Twist the doll's curly hair with your fingers; We can see the disposable paper cup cute baby.

3. Chair: Prepare a few paper cups, a few plastic cotton swabs, a pair of scissors, pins, and double-sided tape to start making; Divide the paper cup into quarters, leave the chair legs, and cut the rest (step2) after cutting it is what step3 looks like on the picture; Fold the chair legs and half the height will do; Then find a good distance, tear off one side of the double-sided tape, and leave the other side equidistant and stick it on the chair surface; Then stick it vertically, and then wrap each leg with double-sided tape in turn; Take a paper cup and cut out a piece to make the back of the chair, hollow out it to make a shape, and fix the back of the chair with double-sided tape.

1. Prepare disposable paper cups, colored handmade paper, bottle caps, glue sticks, scissors, etc.

2. Fold two pieces of blue handmade paper into a bow and stick them on the outer wall of the paper cup decorated with yellow handmade paper.

3. Cut 8 strips of paper 3 cm long and 1 cm wide on blue paper, and 2 strips of paper 5 cm long and 2 cm wide on off-white handmade paper, and make these strips of paper into paper rolls. cut out large "pincer" shaped pieces of paper of crabs on red handmade paper and paste them on off-white paper rolls; Cut out small "hook" shaped pieces of paper on the crab legs on off-white handmade paper and paste them on a sky-blue paper roll.

4. Stick the blue and black round pieces of paper on the bottle cap to make crab eyes. Glue the yellow paper roll to the cap.

5. Glue the crab's eyes and legs to the paper cup. Use a colored pen to draw the crab's mouth on the wall of the cup. A paper cup crab is ready.

Preparation materials: disposable paper cups, small watering cans, eggshells, latex. Sketch paper: general paper on the line, color pigments and pens.

Production steps: Spray out the desert and spray different shades of yellow paint on the drawing paper to create the initial appearance of the desert.

To draw a cactus, bend the paper cup slightly and dip it in black paint to draw the outline of the cactus.

Trace the details and use a paintbrush to add thorns to the cactus.

Disposable paper cups are a relatively common item in our lives, and we will see this kind of cup at home or on the go. Due to the convenience of this cup, disposable paper cups are used for both family visitors and restaurants to eat and drink. Disposable paper cups are not only found in these two places, but also in other places disposable paper cups and water are also provided to people who need them.

Popular science is coming: At present, domestic disposable paper cups can be divided into three types according to their uses, cold drink cups, hot drink cups and ice cream cups. According to the coating of paper cups, it can also be divided into three types: wax cups, straight-walled double-layer cups and polyethylene coated cups.

The wax cup is similar to the kind of paper cup described in the rumor, the surface is coated with a layer of wax used to separate water, and regular manufacturers will use food-grade paraffin, and it will not cause harm to the human body if you accidentally drink it.

If you want to fill a hot drink, you need to add another layer of emulsion, and the straight-walled double-layer cup uses this coating, and because the double-layer cup has good heat insulation, it is often used as a hot drink cup and ice cream cup.

The polyethylene coated film cup is covered with a thin layer of polyethylene on the wall of the cup, which is a new process, the advantage is that cold drinks and hot drinks can cope freely, and the surface is smoother, and the polyethylene itself is non-toxic and tasteless, but in the case of long-term heating, if the selected materials are not good or the processing technology is not good, it may be oxidized to carbonyl compounds. Carbonyl compounds are not easy to volatilize at room temperature, but they may volatilize when hot water is poured into the paper cup, so this is the reason why people sometimes smell strange words in the paper cup. From a general theoretical analysis, long-term intake of this organic compound must be harmful to the human body.

The above is the kind of cylindrical paper cup that we commonly see. But the shape of the paper cup below is a bit weird.

This cone-shaped paper cup is commonly found in airports, and this shape of paper cup is not easy to hold, so people at the airport can only hold the water cup until they finish drinking water, and then they can throw away the cup. Unlike cylindrical cups, there may often be people who put the cup away without drinking the water in the cup. This is undoubtedly wasteful.

For this reason, the water cups at the airport are generally very small cylindrical cups or conical paper cups.

Of course, in general, this design is definitely considered in terms of saving resources, but what are the specific advantages?

The first is that because the conical paper cup cannot be placed, the user will basically throw it directly into the trash can after using the cup, so as to reduce the phenomenon of casual littering.

The second is to save water, in the same height and size of the cylinder and conical paper cup, the volume of the conical paper cup is only 1 3 of the cylinder. That's why some airports use very small cylindrical cups, because one cup is only one sip.

The third reason is that making a conical paper cup will save paper, and the cylindrical paper cup requires two pieces of paper, and more materials are used. There will also be more leftovers than in cylindrical cups.

At the end of the day, it's about saving resources.

1. The simplest scientific and technological small production of disposable paper cups is soil.

2. It is to string two paper cups with a thread, and there is a paper cup at each end of the line, and the line should be longer, so that the children can "play **".

Life is full of tricks, what can disposable paper cups do? Don't underestimate it.

Eco-friendly small bucket (pen holder):

Material: A waste plastic bag is as red as a chain and white, and a paper cup.

Steps: Cut two straps from the white plastic bag, at least five cm wide, from the middle. Twist his acres and grandchildren into thin ropes, and finally knot them together to become a rope oak tease.

Remember to tie a knot first, twist the two ropes and tie a knot, otherwise the rope will not succeed. When the rope is finished, glue it with clear glue. Twist a rope from a red bag, tie it into a bow and stick it to it, and you're done (if you have time, you can draw on the cup).
