Shenzhen Richest Pack Limited plastic packaging bags made to order


Up to now, stand-up pouches are basically divided into the following five types: 1. Ordinary stand-up pouch: The self-standing pouch in the general form, in the form of four-side flaps, cannot be re-closed and repeatedly opened. This stand-up pouch is generally used in the industrial products industry. 2. Stand-up pouch with suction nozzle: The self-supporting pouch with suction nozzle is more convenient to dump or suck the contents, and can be re-closed and repeatedly opened. It can be considered as the combination of the stand-up pouch and the ordinary bottle mouth. This stand-up pouch is generally used in daily necessities packaging for liquids, colloids, semi-solid products, etc., such as beverages, shower gels, shampoos, ketchup, cooking oils, and jelly. 3. Stand-up pouch with zipper: The self-supporting pouch with zipper can also be re-closed and repeatedly opened. Since the zipper form is not closed and the sealing strength is limited, this form is not suitable for encapsulating liquids and volatile substances.

According to the different ways of edge sealing, it is divided into four sides and three sides. The four sides are that the product packaging has a layer of ordinary edge sealing in addition to the zipper seal at the factory. When using it, the ordinary edge banding must be first torn. The zipper is used to achieve repeated sealing, which solves the disadvantage that the zipper edge strength is small and is not conducive to transportation. The three sides are directly sealed with a zipper as a seal, which is generally used to hold lightweight products. Zippered stand-up pouches are typically used to pack lighter solids such as candies, biscuits, jellies, etc., but four-sided stand-up pouches can also be used to pack heavier products such as rice and cat litter. 4. Imitation mouth type stand-up pouch: The imitation mouth type stand-up pouch combines the convenience of a stand-up pouch with a nozzle and the ordinary stand-up pouch. That is, the function of the nozzle is realized by the shape of the bag itself. However, the self-supporting bag of the mouth-like type cannot be repeatedly sealed, and therefore, it is generally applied to the packaging of disposable liquid, colloidal, and semi-solid products such as beverages and jellies. 5. Shaped stand-up pouch: It is a new type of stand-up pouch of various shapes produced according to the needs of packaging, based on the traditional bag type, such as waist design, bottom deformation design, handle design and so on. With the advancement of society and the improvement of people's aesthetic level and the intensification of competition in various industries, the design and printing of stand-up pouches has become more and more colorful, and its forms of expression have become more and more. The development of special-shaped stand-up pouches has gradually replaced the status of traditional stand-up pouches. the trend of. The purchasing power of fast-moving consumer goods is also growing, and the rapid development of the fast-moving consumer goods market has also driven the rise of the food packaging industry. Nowadays, the types and use of food packaging are very extensive. Good packaging enables products to establish a high-quality image, improve product competitiveness and promote product sales. There are many ways to classify food packaging. If classified according to technology, it can be divided into: moisture-proof packaging, waterproof packaging, mildew-proof packaging, fresh-keeping packaging, quick-freezing packaging, breathable packaging, microwave sterilization packaging, aseptic packaging, pneumatic packaging, vacuum packaging, deoxidizing packaging, blister packaging, and stickers. Body packaging, stretch packaging, retort packaging, etc. The above various packages are made of different composite materials, and the packaging characteristics are corresponding to the requirements of different foods, and can effectively maintain the quality and stable function of the food itself.

In today's society where homogenization competition has obvious interests, the competition of nozzle bags is one of the powerful competition methods in the packaging industry. Later, similar penguin bags and stand-up pouches appeared, but many people did not know the relationship between the three. In fact, these three kinds of bags are essentially the same. The combination of the mouth bag and the stand-up bag is a penguin bag, also called a nozzle stand-up bag. The stand-up pouch was the first to appear, and evolved from the basis of the development of the nozzle bag. Finally, because the mouth bag was somewhat like a penguin, the penguin bag was opened. The nozzle self-standing bag is divided into an upright type and a diagonal type according to the position, and has a long mouth type and a short mouth type according to the shape, which is convenient and practical and beautiful, and replaces the traditional glass bottle, aluminum bottle and the like, thereby greatly reducing the production cost. The nozzle stand-up pouch is the fastest growing packaging material in the world in the past few years, and the future development is bound to have unlimited potential. In the United States, the average annual use of self-standing bags is as high as 17 billion, and the European market is close to 19 billion. Most of the washing liquids and softeners in Japan and South Korea use this type of packaging. Shuangyashan Plastic Bag Printing Factory _ plastic packaging bag custom-made packaging material composite, is the combination of different materials of film materials through equipment or adhesive, in order to improve the mechanical properties, printing performance, heat sealing strength of the packaging bag Gas barrier, water vapor barrier, light blocking, firming performance, medium resistance (oily resin, alcohol, pepper, etc.), can better protect products in high temperature environment, low temperature environment, and freezing environment. The composite method of packaging material can be divided into: 1, solvent composite, 2, solvent-free composite, 3, co-extrusion composite. 1. Solvent compounding, which can be divided into dry type and wet type by coating liquid adhesive together, dry type viscose flux is non-water-soluble flux, and wet type adhesive flux is water-soluble flux. The utility model has the advantages that the coating is convenient and uniform, the composite strength is easy to control, and the packaging bags with different requirements can be selected with different performance adhesives, and the operation is flexible. The disadvantage is that the flux and adhesive will have a risk of spillage, residue on the surface of the material, contamination of the filler, and does not meet industry packaging standards. Special management is required for the storage and discharge of flux. 2, solvent-free composite, through the fusion coating adhesive together, the advantage is to eliminate the risk of flux spillage, the packaging bag material is more secure, the production environment is more safe and hygienic, to prevent the risk of secondary pollution of materials. The disadvantage is that the risk of the adhesive still exists. 3, co-extrusion compounding, by melting the different material particles at the same time and co-extruding, the crucible is not completely solidified, and the film is composited. The advantage is that the risk of flux and adhesive is eliminated, and the production environment is safer and management is more convenient. The disadvantages are professional and technical. It requires big data and experimental support to ensure the material properties of the composite. It is also difficult to control the thickness, uniformity and composite strength of each layer. The above is the main way and combination of advantages and disadvantages of packaging material.
