How to light up the product is actually to make the outer packaging eye-catching. Whether you are a roaster, a coffee shop manager or a coffee bean trader, when your sales reach a certain amount, you will want to abandon the universal packaging bag. To customize the outer packaging of products that meet the brand positioning, the editor of Shanghai Duxia Industry and Trade Co., Ltd. will now come to the custom process of popular science coffee packaging bags.   Coffee packaging bag minimum order quantity (MOQ)      Generally, 30000 MOQs are required. The MOQ is calculated based on the length of a roll of printed film. The specifications of printed films on the market are usually 8000m/r-12000m/r, which is about 30,000 by the size of a 1-pound bean bag. about. The smaller the customized quantity, the greater the loss rate, which means that the order quantity determines the increase or decrease of the unit price. Of course, it can also be ordered at a minimum of 10,000, but the price will be slightly higher.If you know the MOQ, you have to choose the bag type. There are thousands of bag types, some of which are not suitable for packing beans. Here are 3 more common bag types.   Coffee packaging bag type 1. Stand-up pouch (doypack) for packaging coffee beans    This kind of bag is composed of front, back and bottom. It is three-dimensional and can stand up. It can be equipped with a self-sealing

     Puffed food is a loose or crispy food made from cereals, potatoes, beans, fruits, vegetables, or nut seeds, etc., using puffing processes such as baking, frying, extrusion, and microwave. Although the safety of nutrients and additives has been criticized by the world, its crispy taste and variable taste are still the favorite of many young people.     Common puffed food packaging forms are mainly divided into three types: plastic flexible packaging, plastic barrel (box) and paper barrel packaging. The latter two types of packaging have good stiffness and can effectively protect the puffed food inside from being crushed. However, plastic barrels (boxes) have poor airtightness and a short shelf life. In contrast, paper barrels are covered with high-barrier aluminum foil. It is sealed with a cover film with excellent sealing performance, which has a good quality preservation effect, but the cost is correspondingly high. Therefore, the most common puffed food package on the market is an inflatable plastic flexible package. Inflatable plastic flexible packaging is a form of packaging: after food is put into a flexible plastic packaging container, it is vacuumed or not, and then filled with protective gas, such as nitrogen or carbon dioxide, and then sealed.          According to different types of inflation, it is divided into two types: air-filled plastic flexible packaging and nitrogen-filled plastic flexible packaging. According to this principle, the inflatable body constructs a barrier between the crispy and fragile puffed food and the package to exert cushioning

Retort packaging bag Packaging requirements: for meat, poultry, etc. packaging, the packaging is required to have good barrier properties, resistance to bone puncture, and sterilization under the conditions of cooking without breaking, cracking, shrinking, and odor. Design structure: Transparent category: BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPPPET/PVDC/CPP, GL-PET/BOPA/CPP Aluminum foil: PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP Design reason: PET: high temperature resistance, good rigidity, good printability and high strength.

Modified PE is a variety of PE blends (co-extrusion), with

    In today’s fiercely competitive market environment, it is very important to create a memorable brand packaging image, which also puts forward higher professional requirements for each packaging person in material understanding and process application     Laminating is a surface processing technology after printing,    Next, we will explain one by one from the material properties and process selection classification.   Sort the film according to the glue method Instant film:The film itself does not have glue. It needs to be coated with glue during production. The operation is relatively difficult. Workers need to grasp the thickness of the glue. It is suitable for the production of embossed products after film coating and silk screen pearlized film film products. The production cost is relatively Lower. Pre-coated film:    The film itself has glue, no glue is needed during production, and the operation is simple. It is suitable for the film of dark ink. It is less affected by the ambient temperature. Care must be taken when selecting products that require embossing and pearlescent. You can choose a thickening type Pre-coated film to solve.   Summary:    Compared with the instant film, the pre-coated film is relatively environmentally friendly, reduces pollution, and has no damage to the human body; it will not affect the quality of the film due to different paper properties or different ink colors; but the cost is higher because the pre-coated film Coating products are printing consumables, and the price cost of the printing factory

    Vacuum packaging bags, deoxygenated packaging bags, and retort packaging bags are more common packaging forms, but what are the common points and differences among the three? This article will introduce the applications, commonalities and differences of these three types of packaging. 1.Vacuum packaging bag      Vacuum packaging is also called evacuated packaging. It exhausts the air in the package as much as possible, reduces the volume of the packaged material, makes the packaged material close to the packaging bag and is not easy to move, avoids impact with the packaging, and can prevent oxidation of the content. The multiplication of bacteria and anaerobic bacteria makes it easy to carry, not easy to break, and can extend the shelf life of the contents.  2.Deoxygenated packaging bag     The deoxygenated packaging bag does not need to exhaust all the air in the package, but put a deoxidizer in the package to deplete the oxygen in the package. The growth of a bacteria prevents the oxidative deterioration of the packaged product to extend the content. Plastic flexible packaging with a shelf life. 3.Retort packaging bag     The plastic flexible packaging used for high-temperature steaming or water-boiled sterilization is a retort packaging. The packaging must be emptied first. Otherwise, it is difficult for the air in the packaging bag to transfer heat to the contents to kill bacteria. In addition, the air in the packaging will rupture the packaging bag due to thermal expansion. 4.The common points and differences

Introduction    Since milk is a fresh drink, it has very strict requirements on hygiene, bacteria, temperature and other aspects. Therefore, there are special requirements for the printing of packaging bags, which makes the printing of milk packaging film different from other printing technology characteristics. The selection of milk packaging film must meet the requirements of packaging, printing, processing, storage and transportation, and hygiene. At present, the commonly used film material is mainly polyethylene (PE) co-extruded film, which is a polyethylene resin through melt extrusion and blow molding.   Types of film for milk packaging    According to its layer structure, it can basically be divided into three types.     1. Simple packaging filmIt is generally a single-layer film, which is produced by various polyethylene materials with a certain proportion of white masterbatch and film blowing equipment. This kind of packaging film has a non-barrier structure and is hot-filled by pasteurization (85°C/30min), with a short shelf life (about 3 days).      2. Three-layer black and white co-extrusion packaging filmA high-performance composite film made of LDPE, LLDPE, EVOH, MLLDPE and other resins, co-extruded and blown with black and white masterbatch. The black masterbatch added in the heat-sealed inner layer plays a role in blocking light. This packaging film uses ultra-high temperature instantaneous sterilization and hydrogen peroxide sterilization, and its shelf life can reach about 30 days at room temperature.     3. Five-layer black and white co-extrusion packaging filmThe intermediate barrier layer (composed of EVA, EVAL and other high

    Composite packaging materials are made by heat-sealing films with different characteristics with special adhesives to overcome the inherent defects of a single film, and finally can be used in various packaging bags. A. Development status and scope of application of  composite packaging materials       According to statistics, 30% of product competitiveness comes from packaging!     Packaging is the “silent salesman” of goods. In addition to protecting goods, it must also be devoted to beautifying, promoting, and inducing consumers’ desire to buy, so as to enhance the sales competitiveness of goods in the market. All in all, the importance of product packaging is that packaging directly affects the consumer’s psychological orientation and purchasing behavior of customers, so how to make product packaging design cater to consumers’ buying psychology is an important factor in promoting product sales.      As the name implies, composite packaging materials refer to packaging materials in which thin, soft, multi-layer materials are combined through a composite process, so they are also called flexible packaging materials, mainly composed of various plastic products.     With the development of packaging technology in my country, composite packaging materials have also shown new development trends. Generally speaking, composite packaging materials have the characteristics of protection, functionality and decoration. Its specific performance is: ①The packaging should play a protective role during the transportation, storage and use of the product; ②The packaging must reflect the characteristics and uses of the products it contains; ③Packaging should provide consumers with

The rise of cosmetic mask packaging bags     The rise of the attention economy has brought the whole people into the “face-seeing era”. There are many types of skin care products, which are highly sought after by women. Among them, facial mask products are easy to use and cost-effective, and gradually become the most widely used product in cosmetics, and even many men use facial masks. People use the mask to cover the face for a short time to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote sweat gland secretion and metabolism, increase the oxygen content of the skin, and help the skin eliminate epidermal cell metabolism The products and accumulated oils and fats, the moisture and nutrients in the mask penetrate into the stratum corneum of the epidermis, the skin becomes soft, and the skin is naturally bright and elastic. Therefore, facial mask packaging has become an important category in flexible packaging, and more and more companies specialize in making facial mask bags and films. The mask is composed of membrane materials and essences. The essences mainly include water, moisturizers, preservatives, viscosity modifiers, efficacy or plant extracts, soothing ingredients, stabilizers, flavors and pigments, etc. It is rich in amino acids, collagen, vitamins and biologically extracted active substances. Material requirements for the packaging bag of the mask       Therefore, the packaging material of the mask must have: a. Excellent oxygen and moisture resistance; b. Good

    As a flexible packaging material, whether it is used for bag making (three-side sealing bag, self-supporting bag, zipper bag, eight-side sealing bag), or as a roll film, the heat-sealing strength value must meet the standard requirements, so that it can be sealed, compressed, Anti-mechanical shock, boiling, steaming and other aspects provide safety protection for the package contents. Heat-sealing strength is a very important physical index of composite film, a key control point in the bag making process, and a major issue that has caused disputes between packaging material producers and users. Composite strength is the focus of frequent discussion and attention in the flexible packaging industry. Maybe everyone has summarized a set of effective control schemes. Now based on production practice experience, we will discuss the factors that affect the heat seal strength to stabilize packaging during the use of composite film. Provide some reference opinions on product quality, reduction and elimination of various potential risks caused by abnormal heat seal strength. A. Definition and standard of heat seal strength      Heat-sealing strength is also called heat-sealing strength, bonding strength, sealing strength and sealing strength, etc. It is the inner layer material of the composite film that bonds the molten materials together by heating and pressing, and after cooling to normal temperature, the bonding There is a certain degree of firmness, and the firmness of this fit is the heat seal strength. According to the specified sampling and testing methods, the specific value of the sample can

The flexible packaging film raw materials we currently use are basically non-degradable materials. Although many countries and companies are currently working on the development of degradable materials, there are currently no alternatives that can be mass-produced for degradable materials that can be used in flexible packaging. As the country pays more and more attention to environmental protection, many provinces and cities have successively issued regulations that restrict plastics and even “ban plastics” in certain areas. Therefore, for composite flexible packaging companies, a correct understanding of degradable materials is a prerequisite for making good use of degradable materials and realizing green and sustainable packaging. A. Definition and classification of degradable plastics. The degradation of plastics refers to the process in which the structure of plastics undergoes significant changes and performance loss due to environmental conditions (temperature, humidity, moisture, oxygen, etc.). The degradation process will be affected by many environmental factors. According to its degradation mechanism, degradable plastics can be divided into photodegradable plastics, biodegradable plastics, photo-biodegradable plastics and chemically degradable plastics. Biodegradable plastics can be divided into completely biodegradable plastics and incomplete biodestructive plastics according to their degradation methods. 1. Light-degradable plastic Light-degradable plastic means that the plastic material undergoes a cracking and decomposition reaction under sunlight, causing the material to lose its mechanical strength within a period of time after sunlight exposure, turning into a powder, and some can be further decomposed by microorganisms. Natural ecological cycle. In other words, after the molecular chain of photodegradable plastic is destroyed by
