How to choose a food packaging box? How to choose food packaging bags

Nowadays, food blister packaging can be seen everywhere, in supermarkets, fruit stores, vegetable fields, you can see the figure of blister packaging, in daily life, we sometimes buy some blister packaging to hold food, what kind of blister box is safe? First of all, when consumers buy these blister packaging, they should see whether there is QS mark, production license number, manufacturer, production address and other information, so as to improve the quality assurance of blister packaging products. Secondly, you should choose products with good packaging, pay attention to the production date and shelf life, and try to choose packaging products within the shelf life to prevent bacteria and mold.

Again, we look at the appearance. We try to choose colorless and transparent products without decorative patterns. We can also smell the smell, but we can first smell whether there is any peculiar smell to prevent it from smelling with food when used, which will affect food safety.

Finally, we have to pinch whether the blister box is too soft, and try not to choose a product that is too soft to pinch. Xukang's blister packaging has a smooth surface and uniform color.

According to the scope of its application, food packaging bags can be divided into: ordinary food packaging bags, vacuum food packaging bags, inflatable food packaging bags, boiled food packaging bags, retorted food packaging bags and functional food packaging bags.

At present, with the continuous improvement of domestic packaging technology, the rapid development of the Internet and the continuous integration of packaging resources, the Internet is now used as the entrance to packaging. It's no longer the same as before, looking for factories first, and the quality is not guaranteed. "Hui Packaging" integrates high-quality resources in the market to provide one-stop packaging services, hoping to help you.

Choose the right food packaging bags.

The following points should be paid attention to when selecting and using qualified plastic packaging bags for food:

The outer packaging of plastic packaging bags for food should have Chinese logos, mark the factory name, factory address, product name, and indicate the words "for food" in a conspicuous place. After the products leave the factory, they are accompanied by a product inspection certificate.

2.Plastic packaging bags for food are odorless and odorless when they leave the factory, and plastic packaging bags with special odors cannot be used for food packaging.

3.Colored plastic packaging bags (dark red or black and other colors currently used in the market) are not used in food packaging. Because this kind of plastic packaging bag is often made of recycled plastic stool materials.

4.Try to choose materials that are not coated or coated. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used.

This not only brings difficulties to the materials and reuse of products after they are scrapped, but most of the paints themselves are toxic, and if people eat these packaged foods, it will cause great harm to people's bodies. In addition, the coating and plating process also brings great pollution to the environment. For example, the paint volatilizes toxic solvent gases, and the waste liquid and waste residue pollution containing chromium and other heavy metals are produced during electroplating.

Therefore, it is necessary to use packaging materials that are not coated and coated with virtual holes as much as possible.

5.It is best to buy food in large shopping malls, not street stalls.

6.Due to the characteristics of plastic packaging bags for food that are not easy to degrade, they will cause environmental pollution, so it is best to choose green packaging materials when purchasing food. Paper is currently the most widely used green packaging material.

Therefore, it is best to choose the original paper packaging when purchasing food, and biodegradable plastics are also acceptable.

In the 21st century, with the improvement of people's living standards, in addition to the improvement of the quality requirements of the goods themselves, the packaging requirements for the goods are getting higher and higher, not only requiring the packaging of goods to be beautiful, economical and practical, but also to meet the requirements of environmental protection. In today's pursuit of green, we should advocate green packaging. In order to adapt to this green environmental protection storm, China's packaging industry is undergoing a profound revolution in terms of design concepts, material selection, production technology, product performance, waste disposal and other aspects.

Let's fight the "sugar-coated shells" to the end.

Hohhot packaging box: "Zongzi fragrant, fragrant kitchen." Artemisia leaves are fragrant, full of fragrance.

The peach branch was inserted on the gate, and the wheat was yellow when he went out. Duanyang here, Duanyang there, Duanyang everywhere. "The Dragon Boat Festival is approaching, and every household begins to purchase a variety of delicacies to celebrate the festival, so do you pay attention to what materials are used to package the delicacies?

Popular science of food packaging labeling.

I believe that everyone has seen some trademarks and marks under the food blister packaging when buying food blister packaging with gourmet products, and the general plastic products will have the corresponding symbol of its safety level, that is, the symbol of the triangle with an arrow loop is marked with Arabic numerals, ranging from 1 to 7 levels.

The meaning of these numbers represents.

At the bottom of the food blister packaging, there will be a triangular shape of the plastic ** symbol symbol, and the number is a few to represent several levels of material. It is divided into seven grades, from level one to seven, and the higher the number, the stronger the hardness.

1 Grade 7 products are mainly PET food blister, HDPE food plastic, PVE food plastic, LDPE food plastic, PP food blister, PS food blister, PC food plastic.

Application for each material.

In the food blister box, only grade 1, grade 5 and grade 6 materials can be blister molded, and the other materials are injection molding or blow molding.

Grade 1 material PET food blister packaging.

It is often used to make plastic boxes, beverage bottles and other products, and the transparent fruit boxes and cake boxes that people often buy are packaging products made of PET sheet blister, which are food-grade safe plastic materials. It is only suitable for warm drinks and cold drinks, but the substances that dissolve the jujube album at high temperature are harmful to the human body, so PET materials are mostly used for fruit blister or vegetable packaging.

Grade 5 material pp food blister packaging.

Polypropylene, can be made into any food plastic packaging, such as food special plastic bags, food plastic boxes, food straws, etc., PP is the only plastic that can be put into the microwave oven heating, and has high strength and folding resistance, 50,000 times -20 times will not be damaged when falling from a height. Food-grade PP sheets are commonly used with quick-frozen dumplings and microwave heating food packaging, which can be reused.

Grade 6 material PS food blister packaging.

Polystyrene, often used in the production of bowls of instant noodle boxes, fast food boxes, disposable food packaging boxes, etc., has good cold resistance. Food-grade PS sheets are commonly used in containers such as yogurt cups. However, this material is too hot to release chemicals, so it is best not to pretend to be used to pack hot food.

Bakery companies are increasingly preferring to use transparent boxes for packaging, and transparent plastic boxes have a unique and significant transparency advantage! The product packaging can make it clear to customers at a glance, and the transparent blister products used in the early days have simple packaging, soft packaging, and are not high-end enough. Later, PS injection molding box was gradually used, due to the high transparency of PS injection box, it can display the product in an all-round way, the thickness of the product can be adjusted by using the injection molding process, the product feels hard, it seems very high-end, and it is also very popular with consumers.

In order to solve this problem, the thickness of the product is required to be thick, and the packaging is often broken during transportation, resulting in an increase in costs. Food factories urgently need to find alternatives, at this time PET injection boxes appeared, PET plastic boxes are transparent, and can not be broken, the thickness of the box does not need to be as thick as PS boxes, saving materials, the price is slightly lower than PS boxes, and soon many companies on the market have changed to PET injection boxes, and there is a trend of replacing PS boxes.

Because the production process of PET injection boxes is more complex than PS injection boxes, there are not many enterprises that can form large-scale production, and the original production of PS injection boxes is gradually withdrawn from this market competition because they do not understand the PET process.

At present, PET injection box manufacturers are limited to the original enterprises that have opened PET plastic bottles, they have PET injection molding technology, and can use existing equipment to produce, the cost of investment is low, and it is logical to share the cake of this market. The baked goods packaging box has gradually transitioned from the original PS material to PET material.

I need it here, can you briefly say **?

Steps: 1. Before customizing snack food packaging bags, manufacturers need to locate the product packaging style and the information to be expressed, determine the specifications, materials, thickness and bag type of Liangshan bags, and make packaging bag artwork according to the design of their designers or packaging factories according to these information.

Only in 2, plate making, after the artwork is determined, a professional technician is required to separate the color of the pattern, repair some unclear places, and call the slag file as a document, and after the document is completed, more than a dozen processes are needed to complete the plate making;

3. Printing, after the raw materials are prepared, the surface film is printed with a high-speed printing machine;

4. Composite, the surface film after printing.

First of all, you first determine the size of the packaging bag, and the rest of the time you find a Li Pin packaging bag company, tell them your design requirements, provide you with food and food patterns, and ask their designers to design a few packaging bags and the size of the bag and ** single for your approval, you can place an order after you are determined, (remember to bargain).

You can also ask them to provide you with a few samples to show you first, and you can choose one of them.

Customized food packaging bags mainly contain two costs: the cost of the bag, which is calculated according to the size of the bag itself, the general packaging bag manufacturers will put the material, labor, ink, machine damage, and freight and other comprehensive calculations, the second cost is the royalty, this royalty is estimated that many people are not clear, because the packaging bag printing is gravure printing, this gravure is also called point engraving, similar to the official seal, is a printing tool, engraved with the printed pattern, printed text information, This royalty is based on the size of the bag. There is also the color of the printing, how much is it, and how many colors are counted in the design drawing.

Before customizing food packaging bags, manufacturers need to locate the product packaging style and the information to be expressed, such as you make an octagonal sealing food bag, the information contained in the bag: the octagonal sealing bag manufacturer is Guangdong Huangpin Yachi, the size is 15x217cm, and the material is: petvmpetpe.

These are the parameters of the bag, before making the bag, we must clarify these specifications, materials, thickness and bag type, and according to these information, let your designer or the design of the packaging factory make the artwork of the bag, you can design a few more copies, give reference and finally determine the bag.

Secondly, after finding a good packaging factory, if the distance is close, and the food factory with time can find a time to look at the packaging factory and confirm the manufacturer's qualifications, production level, hygiene level, etc. If the distance is far away, you can ask the packaging factory to send some similar sample bags to the food factory, try to install and check the quality of the packaging bag and whether the printed pattern is good.
