What is Food Packaging Bags

Food packaging bags are a type of packaging design. In order to facilitate the preservation and storage of food in life, product packaging bags are produced. Food packaging bags refer to film containers that are in direct contact with food and are used to contain and protect food.

Benefits of Food Packaging Bags

Protecting food:

Food packaging bags can effectively protect food from external environmental factors such as moisture, light, oxygen, etc., thereby extending the shelf life of food. Different types of food packaging bags, such as vacuum packaging bags, inflatable packaging bags, etc., can provide the best storage environment based on the characteristics of the food.

Convenient transportation and storage:

Food packaging bags make food easier to transport and store, especially for fragile or perishable food. Packaging bags can provide additional protection and reduce damage during transportation.

Improving food safety:

By using packaging materials that meet food safety standards, it is possible to effectively prevent food contamination and protect consumer health. For example, use non-toxic and odorless materials, and avoid using recycled plastics.

Promoting environmental protection:

Modern food packaging bag design emphasizes environmental protection, and many packaging bags are biodegradable or recyclable, reducing their impact on the environment. Choosing green packaging materials such as paper or biodegradable plastics can help reduce environmental pollution.

Information provided:

Food packaging bags usually indicate information such as production date, shelf life, ingredients, etc., which consumers can use to make more informed purchasing decisions. At the same time, Chinese labeling and product inspection certificates are also important guarantees for food safety.

Promoting sales:

Exquisite packaging design not only protects food, but also enhances product attractiveness, increases consumer desire to purchase, and thus promotes sales.

Types of Food Packaging Bags

1.Wrapper pouches
Wrapper pouches are great because they allow you to wrap your product up without worrying about any damage. Using these pouches is a great way to express your creativity while giving the customer reusable product bag packaging. If you request it, we can make custom wrapper pouches specifically for your brand.

2.Liquid pouch packing
Liquid pouch packing is excellent if you serve many condiments, sell frozen lemonade, or ship any other liquid item. Different types of pouch packaging allow people to see the inside contents and their color. Further, they’re great for those who need to refill industry containers in a simpler and cleaner manner. They also allow you to customize the bag’s contents; these pouches are versatile and come in both dual and separated varieties. If you’re not the best with designs or additives, you can easily add a sticker with your logo, a crazy texture, or a reusable straw to your pouch!

3.Poly mailer bags
The most common of the different types of bags for packaging are poly mailer bags. They are inexpensive, and you can customize them with your logo or any design or color. Poly mailers are a great alternative to boxes for small business owners to use for clothes, accessories, and other lightweight objects.

4.Foil sealed pouch bags
Foil sealed pouch bags are great if you ship food items or anything susceptible to melting. In addition, you can put a sticker logo on your packaging and include more customizations on the inside in a separate plastic bag.

Material of Food Packaging Bags

01.

High density polyethylene (HDPE)

HDPE is one of the most common plastic bags used in the world. This semi-translucent, lightweight plastic bag has a high resistance to temperature changes, water and vapour. It also has high tensile strength, and has been approved by the FDA as it meets their food handling guidelines. This type of plastic bag will most commonly be found at grocery and convenience stores, delis, or restaurants.

02.

Low density polyethylene (LDPE)

LDPE bags are most commonly used as food and utility bags as it is made from low density polyethylene. They have high clarity and are extremely breathable too, making them a popular choice in the fast-paced setting of a commercial restaurant. While they aren’t as strong as HDPE bags, LDPE also meet the FDA food handling standards and can be used to store bulk food items like fresh fruits and vegetables. LDPE bags can also be used for heat sealing purposes due to its low melting point.

03.

Linear low density polyethylene (LLDPE)

The biggest difference between LLDPE and LDPE plastic bags is that LLDPE food bags have a thinner gauge, but with the same strength. Thus, allowing the user to “down-gauge” and save money without compromising on quality! LLDPE bags also meet the FDA’s food handing requirements and can be used to store food in both refrigerators and freezers.

04.

Polypropylene (PP)

Unlike the other varieties of plastic bags, polypropylene bags are not breathable and can be used to store food products such as herbs, buts, candies to enhance their product shelf life for retail situations. Such plastic bags also display excellent chemical resistance and strength, and are FDA approved. Additionally, polypropylene bags are clearer than LDPE or LLDPE bags for enhanced product visibility.

Application of Food Packaging Bags

Physical protection
The food stored in the packaging bag should avoid extrusion, shock, vibration, temperature difference and other phenomena.

Case protection
The outer shell can separate the food from oxygen, water vapor, stains, etc. Preventing leakage is also a necessary factor in the packaging design. Some packages include desiccants or release agents to extend shelf life. The removal of air from vacuum packaging or bags is also the primary method of food packaging. Keeping food clean, fresh and safe within the shelf life is the main function of the packaging bag.

The same packaging
Packing small items of the same kind in one package is a great way to save on bulk. Powders and granular objects are to be encapsulated.

Convey the message
Packaging and labels tell people how to use, transport, recycle or dispose of packaging or food.

Marketing
Marketing often uses box labels to encourage potential buyers to purchase an item. Packaging design has been a very important and changing phenomenon for decades. Marketing communications and graphic design are applied to the outer box and (for some reason) to the highlights of the sales display.

Safety
Packaging can play an important role in reducing transportation safety risks. Food packaging also prevents food from being classified as other commodities. Food packaging can also reduce the likelihood of stealing food. Some food packaging is sturdy and has anti-counterfeiting signs, which play a role in protecting the interests of merchants from loss. Labels such as laser logos, special colors, and text certification can be affixed to the packaging bags. In addition,retailers, in order to prevent theft, put electronic surveillance tags on food packaging bags so that consumers can get the store exit and eliminate the magnetic force.

Convenience
Packaging can be easily added, loaded and unloaded, stacked, displayed, sold, opened, repacked, used and recycled.

Process of Food Packaging Bags

Draft design
Before the production of packaging bags, it is necessary to have a draft design of the packaging bags, which is completed by the customer and the designer, including: pattern design, color matching, font selection, company information, product introduction, contact information and other content, as well as the size data of the packaging bags.These need to be communicated step by step, the more detailed the better, and finally need to be proofread and confirmed word by word to avoid unnecessary losses.

Plate-making
Plate-making is after the confirmation of the draft design, it needs professional plate-making technicians to process the color separation of the draft. The general steps of plate-making are: confirm the type of packaging bag, confirm the font line of the packaging bag, confirm the size of the packaging bag, confirm the transition color, confirm the background color, confirm the substrate and other aspects.

Printing
After all the raw materials are prepared, printing begins. Generally, a high-speed printer is used to print the surface film. Each color needs a corresponding plate roller during printing. The plate roller is a concave plate engraving.During printing, the ink flows continuously, because the ink will congeal, a scraper is embedded on the roller. The function of the scraper is to scrape off the excess ink from the convex part of the plate roller, so that the concave plate roller I can print the designed pattern. If there is dust on the doctor blade, there will be strip-shaped ink pollution, and dot-shaped ink pollution is caused by the ink splashing on the packaging film during the rolling printing.

Product inspection
The inspection is to input the printed matter of the standard model into the computer, and then pass the printed film through the white screen controlled by the computer. When a defective product appears, a black mark will be directly pasted on the rolling film.

Compounding
After the surface film is printed, compounding begins. Compounding is the process of combining the printed surface film with the heat-sealable inner film on a high-speed laminating machine with or without solvent. The compounding generally adopts the dry and wet compounding method, that is, the printed surface film is coated with glue and then enters a drying tunnel to bake for 2 minutes, and then compounded with the middle layer inner film, the compounding tension is about 5.6kg.

Curing
Put the compounded film into the curing room for curing.The purpose of curing is mainly for the glue between the multilayer films to be firmly adhered.The curing is generally cured at 55 ° C or 65 ° C for 48 to 72 hours. . If the time and temperature do not meet the requirements, there will be a phenomenon that the packaging film is not tightly laminated and the finished bags are layered. Curing can make food packaging bags not easy to delaminate, and some of the rolls of packaging bags with special properties need to be cured for 72 hours to achieve the effect. This is also a major reason for the relatively long production period of customized special performance bags.

Slitting
After inspection, the film needs slitting.

Bag-making
The last step is bag-making. In this step, the bag-making technician should adjust the operation procedures of the bag-making machine to ensure that the edges of the color-printed packaging bags are good and airtight.The temperature of the hot knife and the running speed of the bag-making machine should be well controlled. When making bags, the machine will directly make a roll of film by the machine for automatic bag making. During the bag making process, the edge will be automatically sealed.

How to Choose the Right Food Packaging Bags

Size

According to the quantity and weight of the food item, you must select the right size of the pouch. It's always better to keep a little extra space in the bag.

Type

The first thing to do is decide on the food item you are packaging. Once you have identified this, you can quickly choose one of the options that will later be discussed in this article.

Sustainability option

Purpose

Knowing the purpose of the pouch is also an important thing to consider before choosing. They can range from displaying your items in stores, putting medicinal food in it, or any other specific needs. Understanding what the use will is necessary to make the right decision.

Reusability

Another thing that you must consider is whether the pouch will be reused or the food item will be consumed occasionally. In such cases opt for stand-up pouches or gusset pouches as they can be resealed and give a longer shelf life to the food.
