Why use food packaging film?
The demand for food packaging film shows a continuous upward trend, mainly because food packaging film can be used in different food packaging and processing work, and has a very good protective effect on food, so in most cases, people will choose to use food packaging film as a protective film for preservation and storage.
The role of food packaging film
To a certain extent, food packaging film can shield small molecular gases, liquids, water vapor, aroma, वगैरह।, so it can play a role in the preservation of food quality, ताजगी, and flavor and prolong shelf life. It is not only widely used in the food packaging industry, but also plays a very important role in pharmaceutical packaging.
Food packaging film plays a protective role on food, protects the freshness of food, and prevents dust, bacteria, आदि. It greatly facilitates the circulation of food.
1. Protect food and extend the shelf life of food:
Protect the appearance quality of food, promote food competition, increase food sales, and generate certain economic benefits.
Protect the original quality of food and prolong the shelf life of food
2 Packaged food is convenient for circulation
During the whole circulation process of food, it has to be handled, loaded and unloaded, transported, and stored, which is easy to cause damage to the appearance and quality of food. If it is directly irradiated by sunlight and light, and at a high temperature, it is easy to cause food to oxidize, change color, and taste bad. and other phenomena, such as the use of corresponding vacuum packaging, inflatable packaging, आदि. after inner and outer packaging, the food can be well protected to avoid damage.
The food itself has certain nutrients and moisture, which are the basic conditions for the production and reproduction of bacteria, mildew, yeast, आदि. When the temperature of food storage is suitable for their reproduction, it will cause food spoilage. If the food is aseptically packaged or subjected to high-temperature sterilization, refrigeration, and other treatments after packaging, it will prevent the occurrence of food spoilage and prolong the shelf life of the food.
3. Packaged food is convenient for circulation
Some packages are containers for food circulation. Such as bottled wine, beverages, canned food, field-packed milk powder, आदि. These packaged bottles, cans, and bags are not only packaging containers, but also transfer tools for food circulation and sales. It brings great convenience to food circulation.
4. Increase the variety of convenience foods
Fresh food that is convenient for consumers, such as quick-frozen dumplings, packaged meals, fruits, aquatic products, वगैरह।, can be convenient for people to eat.
5. Prevent food contamination:
उदाहरण के लिए, when cooking food is in circulation, it must be in contact with containers and human hands, which is easy to contaminate the food. Packaged food can avoid this phenomenon, which is beneficial to the health of consumers.
The advantages of food packaging film:
Food packaging film is one of the basic varieties of BOPP heat-sealing film. It is a polypropylene heat-sealing film made of biaxially stretched using heat-sealing masterbatch on the surface layer. It has lightweight, non-toxic, odorless, नमी रोधित, and mechanical strength. High, good dimensional stability, excellent transparency, excellent printing performance after surface treatment, और इसी तरह.
The food packaging film has high transparency, the product is environmentally friendly and non-toxic, and meets the international standards for environmentally friendly packaging and cling film. During heat sealing, no toxic gas will be produced; it has the right and flawless molding ability for various special-shaped products; the heat sealing film has high transparency and good gloss, which can display the appearance of the product and increase the desire to buy; tough and tear-resistant, Good flexibility, not easy to be embrittled, durable and high tear strength, to ensure that the packaged goods will not be deformed after being stored for a long time.
Features of food packaging film:
The flatness of the film surface is good, which is suitable for high-speed packaging;
Good transparency, high stiffness, low static electricity;
The heat sealing temperature is low, the haze is low, and the sliding property is good;
The film has good heat sealing performance and processing adaptability.
Production Process of Food packaging film:
- Packaging design: Design the layout of the packaging bag according to customer requirements, and then give it to the manufacturer.
- Copper plate making: It is to make the copper plate required on the printing machine according to the confirmation draft of the packaging bag design. The specific plate size should be determined according to the product packaging design in the previous step.
- Layout printing: Install the prepared copper plate on the packaging printing machine, and then print it according to the information confirmed by the customer.
- Composite material: The so-called composite material is to bond the two materials together, and stick the ink surface between the two layers of materials, such as nylon (nylon)/पी.ई (reinforcing material).
- Bag-making and bag-cutting: bag-making and bag-cutting are done on one machine. When the material is compounded, it is placed on the bag-making machine. After debugging the bag-making machine, it can be carried out according to the adjusted size. Heat-sealed packaging bag materials, and finally cut the bag food packaging according to the adjusted size.
The craftsmanship of Food packaging film:
Food packaging films are generally produced by two processes: blow molding and casting.
One is the blow molding process.
Water cooling is cooled by direct contact with the film surface, ताकि इसे जल्दी ठंडा किया जा सके, गोलाकार खिंचाव, इसकी सपाटता कास्टिंग विधि की तुलना में थोड़ी कम है, लेकिन पारदर्शिता लियूयान प्रक्रिया से बेहतर है, और गोलाकार स्ट्रेचिंग में उत्पादित भोजन के लिए एक उच्च अवरोध होता है। खिंची हुई फिल्म की लचीलापन का एक निश्चित प्रभाव होता है.
दूसरा लियूयान प्रक्रिया है.
हाई-बैरियर फूड पैकेजिंग फिल्म को कोल्ड रोल द्वारा ठंडा किया जाता है, and the obtained high-barrier food packaging film has a certain stretch in the longitudinal direction and no stretch in the transverse direction. The integrity is good, and the transparency is lower than that of the blow molding method.
Types of food packaging films
The types of food packaging films include meat product packaging, brewing powder packaging, agricultural and sideline food packaging, seasoning packaging, leisure packaging, roasted nuts, dried fruit packaging, and another food packaging.
Application of food packaging film:
Food categories: biscuits, आलू के चिप्स, snow cakes, cakes, chewing gum, चॉकलेट, hawthorn slices, schema, वगैरह।;
