In daily life, whether it is a shopping mall or a home, beautifully designed and easy-to-use food packaging bags can be seen everywhere. In fact, the food packaging bag is like the personal clothing of the food. It not only protects the food, but also facilitates the storage, transportation and sale of the food. In most cases, the unique and beautiful appearance of food packaging bags is also a weapon that attracts consumers’ attention.
Presumably everyone wants to know how to customize exquisite food packaging bags? Hunan Zekun Packaging, a professional flexible packaging manufacturer, believes that no matter how you want to customize food packaging bags, you must abide by a principle, that is, you must choose a good food packaging bag manufacturer, a powerful and large-scale customized production Only manufacturers can ensure that the customized food packaging bags are more beautiful and of better quality.
The first、Six issues that need to be paid attention to in the customization of food packaging bags:
1. Customized manufacturers must be qualified formal enterprises;
2. The food packaging bags produced by the manufacturer must meet the food safety standards, and the food directly imported should use non-toxic and clean packaging materials, tableware, drinking utensils and containers.
3. The selection of food packaging bag materials should meet the following requirements: degradable or easy to recycle, in line with environmental protection requirements; in line with relevant food containers and packaging materials hygiene standards.
4. Food packaging bags shall be marked on the container and outer packaging of bulk food with the name of the food, production date or production batch number, shelf life, and the name, address, and contact information of the producer and operator.
5. Qualified food packaging must be printed with the “QS” mark when it leaves the factory for sale. Without this mark, it cannot be sold in the market.
6. Food packaging bags must have sufficient thickness and strength, so as to ensure the function of food bags.
The second、When customizing food packaging bags, you should also pay attention to the three elements of material, style and pattern：
1. Food packaging materials
What material to choose to package your food depends on the nature of your product. For example, if you want to pack moon cakes, you need to use high-barrier materials. If you want to pack oily food, you need to use oil-packed PE. There are many composite structural materials in packaging materials, which are determined according to the functional characteristics of the product. This is the most important point of customizing food packaging bags. Choosing the right ingredients can effectively extend the shelf life of food.
There are many styles of food packaging bags that can be processed, and new styles appear every day. Common food packaging bags, in terms of shape, mainly include flat pockets, side sealing bags, stand-up bags, zipper bags, fork ear bags, sling bags, waist-hole bags, vest bags, self-adhesive bags, nozzle bags, special-shaped bags etc. How to choose the style of the packaging bag has the most direct relationship with the nature of the product and the usage habits of consumers.
For your product to be distinctive and attractive, you need to design a unique set of printed patterns for your packaging. Exquisite printing patterns can attract consumers’ attention, increase the desire to buy, and also highlight your brand more. How to design beautiful patterns, which requires your design team to be strong enough.
The third、Food packaging bag customization is divided into 9 steps:
After determining the specifications, material, thickness and bag shape of the food packaging bag, let the company’s designer or professional design and production outsourcing team design the artwork according to these materials. When designing, you must give reference suggestions and finally determine the bag pattern. When designing, pay special attention to the text information on the packaging bag, such as: manufacturer name, ingredients, product introduction, origin, net weight, specifications, food label number, QS certification, health license number, production date, storage conditions, shelf life , edible method, manufacturer’s name, factory address, product barcode and contact number, etc., of which QS and barcode must not be less.
2. Plate making
After the artwork is determined, professional technicians are required to color-separate the pattern and repair some unclear areas. At the same time, more than a dozen processes are needed to complete the plate making, so I will not introduce them one by one here. Visit Shunxingyuan Packaging for inspection.
After the raw materials are prepared, use a high-speed printing machine to print the surface film. When printing, there is a plate roll for each color, and the engraving of the plate roll is intaglio engraving.
After printing, the surface film and the easily heat-sealable inner film are compounded in a high-speed peritoneal machine with special glue.
After compounding, it needs to be cured in a curing room above 45 degrees, in order to make the plastic packaging bag not easy to delaminate.
6. Bag making
After curing, the production of plastic packaging bags has come to an end. At this time, certain skills are required. The technicians must ensure that the edges of the color-printed packaging bags are well sealed and air-tight.
7. Quality inspection
The main items of plastic packaging bag inspection are size (length mm, width mm, thickness um), appearance, overprint error, color difference, peel strength, heat sealing strength, etc.
The length and width are detected by a ruler, and the thickness is detected by a thickness gauge.
The inspection of chromatic aberration is mainly through checking with the standard sealing sample, and the color difference should be consistent at one arm distance. In terms of color, Shunxingyuan Packaging will also use a 50 times magnifying glass to carefully check the color of the printed matter. Generally, the color is combined by the dots one by one. If the color is wrong, the dots will appear irregular. Distribution. Generally, the dots of Shunxingyuan packaging and printing are regular, and the dots are circular.
The inspection of the overprint error is mainly visual inspection to observe whether there is a phenomenon of printing ghosting.
Peel strength and heat seal strength are mainly tested by AGS-5KNG electronic universal testing machine. The detection principle is the same as that of the computer tension meter.
For the plastic packaging bags that have passed the quality inspection, they are packaged and put into the warehouse for unified management for later shipment.
After bagging and storage, Hunan Zekun Packaging will immediately contact the customer to arrange shipment.
