Coffee and tea packaging pouch
Various types of tea and coffee packaging bags and pouch!
Nowadays, in the market, we can see an endless variety of tea and coffee packaging pouch, the main ones being tea and coffee packaging bags. For ordinary people, they don't know why a tea and coffee packaging bag needs so many types. In fact, in the packaging industry, according to the type of bags, they are also divided into many bags. Today, Beite Packaging will show you the types of tea and coffee packaging bags, so that you can understand and use them with confidence!
Three-side sealing packaging bag: As the name suggests, three sides are heat-sealed, leaving one side open for product packaging. It is a common type of packaging bag for tea and coffee. The three-sided pack has two side connectors and a top connector and can be folded or stand upright on a shelf.
Four-sided packaging pouch: After four-sided packaging, the four sides are heat-packed. Usually the entire packaging film is divided into two halves for relative packaging. The overall heat sealing and single-bag cutting methods are used. Production control can achieve good packaging effects by aligning one side. Four-sided packaging products are Cube, good packaging effect.
Stand-up pouch: Stand-up pouch tea and coffee packaging bags are as easy to understand as the name. They can stand up independently and stand on the shelf. So the effect is better and more beautiful.
Self-standing zipper bag: Self-standing zipper bag, that is, adding an opening zipper above the packaging of the self-supporting bag, which is convenient for storage and use and avoids moisture. This kind of bag is flexible, moisture-proof and waterproof, and not easily damaged.
Eight-sided packaging bag: This is a bag type based on stand-up bags. Because the base is square, it can also stand upright. This bag is more three-dimensional, with three planes: front, sides and bottom. Compared with stand-up bags, eight-sided bags have more printing space and product display, which can better attract customers' attention.
Spout bag: The spout bag consists of two parts. The product has a better isolation effect and does not leak. There is an independent nozzle on the top and an independent bag on the bottom. This kind of bag is the choice for packaging liquids, powders and other products such as juice, drinks, milk, soy milk, etc.
Back-sealed bag: A back-sealed bag is a packaging bag in which the edges on the back of the bag are sealed. This kind of bag has no opening and needs to be torn by hand. It is mainly used for washing bags, candy, dairy products, etc.
Special-shaped bags: Special-shaped bags have shelf appeal in various shapes and are a popular packaging form in foreign markets. With the improvement of people's quality of life, special-shaped bags have gradually become a means for Chinese commodity manufacturers to improve their brand promotion and product selling points.
Automatic packaging roll film: The main advantage of roll film used in the packaging industry is that it saves the cost of the entire packaging process. Roll film is used in automatic packaging machinery. It does not require any edge sealing by the packaging manufacturer. It only needs one-time edge sealing during production. The roll film packaging is fully electric and integrated, which can save manpower and financial resources by mechanically packaging tea and coffee bags. But it needs to be used with an automatic film packaging machine.
Can composite packaging bags be reused?
People can use plastic bags to package toys and hardware products, thereby improving the storage effect of the items. Because there is a sealing chain on the self-packaging, the chain can be used to archive the items after they are put into the packaging. The use of self-packaging bags is very simple, and there are many classifications of this kind of packaging, so it is now used in both daily life and production. Many users also have this question when purchasing packaging: Can the packaging bag be used repeatedly?
In fact, there are many categories of ziplock bags now. When purchasing, you can choose directly according to the purpose of use, making the packaging bag more efficient in use. However, in order to avoid waste, many users reuse self-sealing packaging multiple times. In fact, when it comes to packaging bags for daily necessities and clothing, such bags can be recycled, but you must pay attention to the fact that there are no impurities around them. If there is dirt, stop using them to avoid affecting their preservation.
In addition, when using ziplock bags, the air pump can also be used together. The air suction pump can directly discharge the air in the packaging bag to achieve a vacuum effect and save space. This packaging machine also has its unique features. However, when using the suction pump, pay attention to the fact that the connection port of the suction pump does not leak and the suction time is sufficient.
What are the advantages of stand up pouch?
After the self-standing plastic packaging bag is completed, the product must be sealed before being put into the market. So what should you pay attention to when sealing? How to make a seal strong and beautiful? No matter how good the packaging bag is, poor sealing will also affect the appearance of the packaging bag. So what should you pay attention to when sealing plastic packaging bags?
1: Sealing method of single-layer plastic packaging bags.
Ordinary plastic packaging bags are single-layered. Such bags are very thin and can be sealed at low temperatures. High temperatures will burn the bag, so the temperature must be checked repeatedly when sealing. Direct temperature will not burn the bag, and the surface of the bag is smooth. At this temperature is the appropriate temperature. Generally such bags are foot sealing machines.
2: Sealing method of multi-layer composite packaging bags.
Multi-layer composite plastic packaging bags are composed of multiple layers of materials. The bags are relatively thick and PET is high temperature resistant, so such bags can withstand relatively high temperatures. Generally, the bags can be sealed at temperatures up to 200 degrees. Of course, the thicker the bag, the The higher the temperature, it must be inspected before batch sealing to avoid unnecessary trouble during use.
The most important thing for packaging bag sealing is temperature control. The temperature control seal is smooth, beautiful and will not be damaged. Therefore, the seal must be checked at the appropriate temperature. Don't worry about mass production to avoid waste.
Biodegradable materials replace plastic bags to reduce environmental harm
What are the harms caused by plastic bags: Plastic bags bring convenience to people's lives, but the temporary convenience brings long-term damage.
Plastic bags have a low recycling value. In the process of using plastic bags, they are not only distributed in urban streets, tourist areas, and water bodies, but also cause visual pollution on both sides of roads and railways, and also cause potential damage. The plastic structure is stable, not easily degraded by natural microorganisms, and does not separate in the natural environment for a long time. This means that if waste plastic waste is no longer recycled, it will become a pollutant in the environment for a long time and continue to accumulate, which will cause great damage to the environment.
According to statistics, 260 million tons of plastic are used globally every year, of which 170 million tons are disposable.
Store fruits
Vegetables and fruits are stored in plastic bags, which is a scientific way to keep them fresh in winter. The principle is to reduce the oxygen concentration and increase the carbon dioxide concentration to put fruits and vegetables in a dormant state and extend the storage period. However, the storage time should not be too long.
Since vegetables and fruits are organic foods, they contain high water content (60~95%), water-soluble nutrients and enzymes. Intense respiratory activity continues throughout storage. Generally speaking, for every 10℃, the breathing intensity increases by 1 times. Under aerobic conditions, sugar or other organic substances in fruits and vegetables are oxidized and decomposed, producing carbon dioxide and water, and releasing a large amount of ripeness. In the absence of oxygen, sugar does not oxidize but breaks down to produce alcohol, carbon dioxide and a small amount of heat.
However, the concentration of carbon dioxide cannot be increased without limit, only by 10%, and the concentration of oxygen cannot be reduced by more than 5%. Otherwise, in order to obtain sufficient energy for life activities during hypoxia, it is necessary to differentiate more nutrients. At the same time, because the alcohol produced by anoxic respiration remains in the fruits, it will cause the fruits to rot and deteriorate, so fruits and vegetables should not be stored in plastic bags for a long time.
To put fruits and vegetables in a plastic bag, you can open the plastic bag between the mouths for 2 to 3 days, add carbon dioxide and heat, and then apply the bag to the mouth, which can reduce the occurrence of rot and deterioration.
Agricultural influence
The accumulation of waste plastic products in the soil will affect the absorption of nutrients and water by crops, leading to crop loss.
Animal threats
Plastic items discarded on land or in water are ingested by animals and lead to their death. 20 herdsmen on the edge of Qinghai Lake killed nearly 1,000 sheep, causing economic losses of more than 300,000 yuan. Sheep love to eat the oily scraps contained in plastic bags, but they often eat them together. Because the plastic they eat sticks in their stomachs for a long time and is difficult to digest, these sheep's stomachs are full of food and cannot eat any more. Then, they can only starve to death. This condition is common in zoos, pastoral areas, rural areas and in the ocean.
The failure of plastic to degrade naturally has led to many animal tragedies. For example, monkeys, pelicans, dolphins and other animals in the zoo will mistakenly swallow this number. 1 plastic bottle was lost to tourists and then died of pain due to indigestion. Looking at the beautiful and pure sea, just around the corner, there are actually all kinds of plastic garbage floating there that cannot contain the sea water. We took samples from the intestinal tracts of many dead sea birds and found that all kinds of plastics cannot be digested.
Three major development trends in tea and coffee packaging bags
The food packaging of Beite packaging bags has experienced the development process from "packaging" to "packaging" to "design". The evolution of this process is not only the evolution of the packaging concept, but also directly reflects the changes in production methods and consumption trends, promoting the development of the contemporary food industry. In recent years, my country's food packaging industry has made great progress. In addition to innovations in packaging concepts, there are also new developments in packaging technology, packaging equipment, packaging production lines, packaging applications, packaging materials and other fields. In this development process, some trends also deserve our attention and comments.
Prepackaged - Premade pouch & Stand up pouch
As early as pre-packaging was widely promoted a few years ago, my country also has pre-packaging related laws and regulations to regulate food companies. The author calls it the first trend, mainly because of the basic national conditions of my country's development and the high development of pre-packaging in this issue. There is huge room for growth, and future development trends will become even more obvious. At present, it can be directly seen that in the market, tea, rice, melon seeds, dried fruits, flour and other foods are gradually being converted from bulk food into pre-packaged products, which is more in line with the development standards of food business.
This situation is closely related to the safety risks of bulk food. Problems such as unclear production information of bulk food, deterioration and failure, and secondary pollution are prominent and have caused a lot of controversy. The products in question have seriously damaged the rights and interests of consumers and healthy diets, and have also brought some difficulties to food market supervision. Secondly, the upgrading of the food industry has pushed bulk food to the edge of elimination. From the perspective of improving production capacity and improving food safety concepts, the promotion of pre-packaging is worth looking forward to.
Small Package
Pre-packaging is for the safety of bulk food, and food packaging is moving in the direction of smaller and lighter, from the customer's point of view, to portable. A typical example is snack food. The expansion of snack food in the past two years has been amazing. From competitions for online brands to physical store layouts and online marketing, professional competitions have always been everywhere. After the success of nuts, dried fruit products have entered the young group, and compact and lightweight packaging has become one of the important strategies for snacks to enter the office.
The outstanding advantages of small packages are that they are easy to carry, easy to store, and reduce waste, just like their advertising slogan "one small package solves all your worries." The trend of small packaging has long been not limited to snacks, tea products, baked goods, processed meat products and other fields. It has also been widely used and achieved outstanding results, and is very popular among young people. As people pay more and more attention to the exquisiteness of food consumption and create the concept of "light luxury" in consumption choices, small packaging has met people's needs and helped more producers create benefits.
Think tank packaging
Whether from the perspective of pre-packaging or small packaging, food packaging has become very important. In order to meet production needs, intelligent development has become an important production trend. How to save packaging materials and achieve perfect packaging, how to complete high-efficiency and high-quality packaging from high-pressure packaging, how to package different product layers according to different specifications of food, and deal with the actual problems encountered in production needs. Intelligent packaging is an important way to deal with these problems. .
According to the characteristics of food packaging parameter settings, full automation can be achieved. A series of operations from input to sealing and packaging can be completed by machines, which not only reduces labor costs, but also improves the level of automation. Throughout the production process, we must also achieve environmental protection, efficiency, stability and other policies. In fact, the "wisdom" of food packaging lies not only in the packaging method and technology, but also in the concept of packaging, which reflects more wisdom and caters to the development trend of the Industry 4.0 era.
