Cartons Cartons are divided into square, round, cylindrical, triangular, diamond, trapezoidal and spherical packages according to their geometric shapes. According to the simulation form, there are many kinds of natural packaging forms, such as fan-shaped, peach-shaped, orange-shaped, goldfish-shaped, simulated cars and airplanes. According to the structural forms of cartons, there are mainly linear cartons and linear cartons, which are the most common and popular cartons. It is widely used in medicine packaging, especially tablets. Its manufacturing method is to punch the paper cover into creases, cut off the unnecessary parts at the same time, and then fold it by machine or hand and bond the two sides to each other. Common ones are as follows: 1. The structure of the bucket is very simple, without the top cover and bottom cover of the box, and it is folded into a tube shape in one direction. Usually worn outside chocolate and candy. 2. Plug-in carton It is a representative of straight cartons, which are divided into straight and reverse types due to different insertion directions at both ends. ① The insertion structure (tongue) of the top cover and bottom cover of the box is on one surface of the box surface. ② Reverse insertion type: the insertion structure of the top cover and bottom cover of the box (tongue! It is on different sides of the box surface and the box bottom. 3. Bonded carton The carton has no plug-in structure of plug-in carton, and the top cover and bottom are bonded together with drilling agent. This kind of box is suitable for powder and granular products. This is a strong carton. It is the most material-saving carton structure because it lacks an insertion structure and there is almost no cut waste in its net area. 4. Bottom-locked carton It is developed on the basis of plug-in carton. Change the plug-in bottom cover into a locking structure. Because the bonding process is omitted, heavier products can be loaded, such as cosmetics, wine, medicines and other vertical products, so it is favored by the public. Cartons with the same size and volume save more materials than plug-in cartons because the insertion structure of the bottom cover is omitted. Disc-shaped carton The disc-shaped carton has a disc-shaped structure. In fact, except for linear cartons, most of the packaging is of this structure. Disc cartons are widely used. Food, cakes, snacks, groceries, textiles, clothing and gifts can all be packed in this way. Its biggest advantage is that it generally does not need to use adhesive, but uses the method of adding notches to the carton itself to lock it, so that the carton can be sealed. Dish-shaped cartons can be divided into the following forms structurally: 1. Folding carton This kind of carton is composed of folded and pasted cartons, which has the advantages of small box area, convenient transportation and inventory, and economy. Cover tray carton: These are two plates made of two pieces of paper: a cover and a tray. This structure has existed since ancient times and is very suitable for all commodities. (2) Shake the lid carton: This is made of a piece of paper. The tray and the cover are connected together. Suitable for packaging bulk biscuits, sweets, local products, etc. 2. Assemble cartons. Cartons of this kind need not be pasted. According to its structure, it can be divided into two forms: double-layer carton and locking carton. (1) A double-deck carton is a double-deck structure with four side panels. Then, the extension flaps on the four sides are joined to fix the panel, and it is not necessary to use a carton with a drilling compound. According to this structure, the wallboard can be developed into a wallboard with a thickness. This kind of carton is generally suitable for heavy food cakes, gifts and so on. Because of the reinforced wallboard and the windowed or transparent top cover. (2) Locking the box: Locking the box is a popular trend now, because it is reasonable and scientific, and saves the process of root paste. The simplest and most material-saving method is to add a cut on the wall of the disc-shaped carton, and then slightly change the structure of the dust cover to form a locked carton. Most cartons of this structure are used to hold hamburgers and sandwiches. At present, the most widely used cartons in the market are the following kinds made by changing the side flaps and the bottom, which are hooked with each other through the upper and lower cuts to form a lock box: the extension of the side flaps is used as a lock box; Use cartons made of transverse folds and front wall panels; A carton consisting of transverse folds and an extension of the front wall panel. Paper paste box This is a kind of packing box for valuables, such as gold and silver jewelry, jewelry, antiques, single glassware, ceramics, precious medicinal materials, etc. Generally, yellow cardboard is used as the lining. According to the needs, all kinds of paper can be used for internal and external pasting, and sawdust, metal foil, glass and cloth can also be used for pasting. Because the pasting box is not widely used, it is expensive to make by hand. Sister cartons Sister cartons are formed by folding two or more cartons with the same shape on a piece of paper. Its appearance is quite interesting and lovely, and the warm label is suitable for holding gifts and cosmetics. Special-shaped carton Due to the change of the broken line, the structural shape of the box has changed, resulting in a variety of strange and interesting special-shaped packaging boxes. For example, due to the change of the broken line on the wall, the position of the folded plate has changed, resulting in the change of the shape of the carton, and the change of the linear position of the box has led to the change of the box; The bottom and top of the carton are given arc changes, which leads to the change of carton shape; When the number of faces is increased, the polyhedron changes: wallboard is added to produce cartons with windows; Change the wall structure and cover the carton. Handheld Carton Carton Handheld Carton Carton This is a carton designed for the convenience of consumers. It must be carried reasonably: simple and easy to take, with low cost, and the carrying handle should be able to bear the weight of articles and not hinder storage and stacking. The most basic form is that the carton and portable structure are integrated, and there is no need to paste them when assembling. The portable insertion structure is inserted in a certain part of the carton, which not only strengthens the carton, but also divides the interior of the carton into two spaces through the handle, which can be used to put a pair of products in, and the wallboard can also be extended, making it a portable carrying structure. According to this basic structure, it can be made into a portable carton with a special shape. Easy-to-open structure, a packaging function developed with the change of circulation, has been widely used. Because the contents can be taken out with one hand, it has become a favorite packaging form for modern consumers. At present, there are several basic forms: 1 Sewing machine blade This is the simplest opening form known to all, and the tissue box is made of this sewing machine blade. 2. The structure of zipper is widely used. The cutting method can be used on one side of the carton or around the carton; It can also be considered as a structure with unsealing and resealing properties. 3. Nozzle This is the best structure. Peel off the glue from a certain part of the carton as an exit. This form is mostly used for container packaging of food liquids, such as milk and drinks, or punching holes in a certain part of the box. As a pouring outlet or inserting a straw. Expanded Carton Carton Expanded Carton is a kind of POP carton that can help consumers find the goods they want quickly, promote sales and play the role of publicity and advertising. This kind of box can best display goods, so some cosmetics, glassware and other packaging adopt this structure. Shelf structure cartons and cartons Shelf structure cartons and cartons are mainly used to protect products. On the basis of folding boxes, we should consider designing various forms of partitions and shelves to put goods. This is the most effective protection for some fragile products, and it also has a display effect after opening. In a word, the types of cartons and packaging design are the product of the combination of science and art. Different consumption objects and consumption levels. The requirements of carton shape and structural design are also different. It is the pursuit of packaging design to strive for beauty and novelty to express the individual characteristics of various commodities. Reasonable structure and ideal material selection are the requirements of protecting goods, being easy to carry, being easy to sell and display, and reducing production costs, which designers must pay attention to.
