Pillow Type Bags

The material structure of this kind of vacuum-inflatable packaging bag is relatively simple. Matte OPP / PE. After vacuumizing, fill nitrogen to expand the packaging bag, which can effectively protect cornflakes from crushing due to mechanical or external pressure. At the same time, nitrogen can prevent oxidation spoilage of fried puffed food.

Due to the simple material structure, the tightness of the packaging bag is better controlled to ensure that the nitrogen in the packaging bag will be retained for a long time and effectively block the external harmful substances such as water moisture, oxygen and UV lights.

Recyclable vacuum-inflatable bag for chip, Its advantage is that materials can be recycled. As we all know, the inflatable bag for packaging puffed food wastes a lot of materials. Therefore, in addition to ensuring the functionality of the bag, we should reduce the weight of packaging materials as much as possible and use lightweight and recyclable materials to reduce resource waste.

Food grade materials are non-toxic and harmless, BPA free, and have excellent barrier performance, which can ensure that puffed food will not be soft, spoilage or broken within the shelf life.

Aluminized vacuum-inflatable bag for food , The good barrier performance of the aluminized film is fully utilized to block oxygen, moisture, block light, oil resistance and retain food flavor. At the same time, the printed appearance is bright, with metal like special luster 。

When using the automatic packaging machine for packaging, because the aluminized film is resistant to high temperature, special attention should be paid to adjusting the heat sealing temperature and pressure to ensure that the packaging bag has good sealing performance.

Customized vacuum-inflatable bag for chip , Custom printing can perfectly display the company’s brand and product information. The material PET / VMCPP has high barrier performance. After lamination, it can effectively block external moisture, oxygen and indoor-outdoor light. In addition, the packaging bag filled with nitrogen can expand, effectively protect food from crushing due to external pressure, and ensure the safety and reliability of long-distance transportation and long-term storage.

Food grade materials without BPA.

The custom printed black vacuum-inflatable packaging bag has very excellent barrier. After vacuumizing, it is filled with an appropriate amount of nitrogen, which can effectively ensure that the food will not be oxidized and spoilage and prolong the shelf life of the food.

The material used is generally a three-layers structure, and the bottom material is LLDPE, which has good oil-resistance and heat sealing to ensure that the packaging bag is firmly sealed without air leakage.

Materials can be safely recycled. Please protect our living environment.

Recyclable vacuum-inflatable bag for snack food , It is often used to pack some soft and fragile foods, such as popcorn, potato chips, cake, bread, etc. when the package bag is filled with nitrogen and the package bag expands to a certain extent, it can protect the food from being broken and deformed by external pressure and maintain the original shape of the food.

The materials used have good barrier properties. The packaging bag made after lamination will have better sealing performance, ensure that the food will not spoilage and change color due to external pollution, and effectively prolong the shelf life of the food.

Vacuum-inflatable pillow bag for snacks . The following two problems should be considered: 1. Barrier properties of materials. Aluminized film is often used, BOPP / VMCPP or PET / VMPET / PE . 2. As this kind of pillow vacuum-inflatable bag is completed on the automatic packaging machine, the bag former and sealer of the packaging machine are required to meet the standard to ensure that the sealing position of the packaging bag is not pleated, otherwise the packaging bag will leak and the food will soon spoilage.

Matte vacuum-inflatable pillow type bag is often used in the packaging of puffed food, because the matte finish gives a special visual effect and can deeply attract the attention of consumers.

Of course, the tightness of the packaging bag is the most important. On the automatic packaging machine, special attention should be paid to that the heat seal at the intersection of the mid-sealing and the end-sealing of the packaging bag must be firm, otherwise the packaging bag will air leak , because this position may be 2 or 4 layers of materials. Therefore, the horizontal seal of the automatic packaging machine must reach enough pressure. At the same time, The temperature of heat seal shall also be compared and adjusted.

The pillow type vacuum-inflatable bag has a front and back panels, which can print the company’s brand and product information. When the pillow type bags inflates, the printed content can be completely displayed to consumers.

The materials used have the functions of pressure-resistance, light-barrier, oil-resistance, air-barrier and fresh preservation. They can effectively preserve the nitrogen in the bag without leakage, prolong the shelf life of food and maintain its original color, aroma, taste and nutritional value.

Potato chips and popcorn in puffed food are easy to break, and will become soft after moisture absorption and lose the original taste and freshness. In order to solve this problem, we must first choose high barrier materials (aluminum coating), which can effectively block the water vapor and oxygen in the air and the impact of light on food.

Secondly, filling nitrogen is the most ideal choice. Nitrogen can effectively isolate oxygen and prevent food oxidation and deterioration. At the same time, the inflated packaging bag will expand to protect the shape and taste of food.

Cake, bread, popcorn and potato chips in puffed food are soft in shape and contain gas inside. When packaging, first vacuum, discharge the gas in the bag and the gas in food cells, and then fill them with inert gases such as nitrogen or carbon dioxide. When the packaging bag expands, it can effectively prevent the food from being crushed by external force.

All the materials used are high barrier, non-toxic and harmless food grade materials and  BPA free.

Recyclable vacuum-inflatable pillow bag for bread ,Two or three layers of materials, BOPP / VMCPP and BOPP / VMPET / PE are usually used. The materials are highly barrier, which can effectively block air, oxygen and light. At the same time, they have the functions of oil- resistance and fragrance preservation. The packaging bags made of laminated materials are firmly sealed, safe and reliable, and can effectively protect food from crushed ，due to external extrusion during transportation and storage.

Digital printing vacuum-inflatable bag for chips.In order to solve small batch orders and avoid inventory pressure,LIBOPACK can perfectly start the production of each product from 200pcs. no matter how many items you have, you don’t need to make expensive copper-plates, which saves the cost. At the same time, it can achieve one bag /one pattern, highlight the unique personalized design of the product, and promise to deliver in 5-7 days, If you are a start-ups company or plan to launch a batch of new products in the market, please don’t hesitate and contact us quickly.

The vacuum-inflatable packaging roll film shall be used together with the automatic packaging machine. The roll film shall be subject to a series of processes of “forming – filling materials – vacuumizing – nitrogen filling – sealing” on the packaging machine. In order to ensure the heat sealing effect of the packaging bag, especially the heat seal at the intersection of mid-sealing and end-sealing must be firm without air leakage. The thickness of packaging roll film is generally 60-80 microns. If it exceeds this range, the pressure and temperature of the packaging machine should be improved. Otherwise, the production efficiency of the packaging machine will be reduced and the production cost will be increased.

As the packaged food is fried food, it is particularly required that the bottom material should have good oil-resistance. We often choose LLDPE or VMCPP. These two materials have good oil-resistance and heat sealing, which can ensure the safety and reliability of the sealing of the packaging bag without air leakage, so as to prolong the shelf life of the food and retain the original flavor and taste of the food for a long time.
