Professional food tube packaging design and manufacturer in China

We have production experience and design experience in food-grade cardboard tube packaging exported to 86 countries in the world.

We have been developing classic designs and improving the air tightness of paper tube packaging as much as possible to ensure that the internal food can be maintained for a longer time.

The advantage of using custom food tube packaging is a friendly ecology. Today’s consumers have been looking for new innovative methods to reuse, recycle, and reduce waste. These influencing factors will have a significant impact on consumers’ purchase decisions. All recycling fiber paper that constitutes our tube is 100 % recycled, biodegradable

food grade requirements for paper tube packaging

1. Non direct contact food cardboard tube packaging

There are usually food-grade white cards, food film, or aluminum foil on the inner wall of nondirect contact food cardboard tube packaging.

Since it does not directly contact the internal food (the food will have a different internal packaging), the requirements for the sealing performance of the paper tube are not very high. It can pass the standard transportation and drop test.

2. Paper can packaging for direct contact with food

Food needs to be in direct contact with the inner wall of the paper tube, except that the production environment and materials reach food grade. The firmness, tightness, and moisture resistance of the paper tube after sealing are some important technical standards.

Usually, the top is sealed with an easy-to-tear cover or easy-to-pull lids, and the buyer fills the food from the bottom and seals the bottom with a sealed mechanical seal.

As early as 1989, China issued the national safety standard GB/T 10440-1989, hygienic requirements, and size limit sampling plan for cylindrical composite cans. The national standard GB/T 10440-2008 has been improved and specified in 2008.

Style of food grade paper cans

Tinplate cover paper tube packaging

The bottom is connected with the cardboard pipe by pressure, which is not easy to fall off and damage

The top tinplate cover can be customized in different colors and embossed brand red wine is the most used packaging form of this process

Easy Open EndsIt is applicable to non processed foods that need moisture-proof and completely sealed, such as snacks, nuts, powder, coffee and tea, infant formula, noodles and rice, spices, pet food and snacks;

Shaker paper tube lidsShaker lids are usually used for the top cover design of paper tube packaging of powder, salt or condiments.

Sea salt is a common design. We have vibrating drying nets with different diameters

Quality inspection standard


1. The outer surface of the tank body is sunken, obviously folded, and scratched.

2. The sealing part of the end cap should be smooth and tight, and the metal end cap is not allowed

The inner wall shall be free of obvious folds and sundries, and the folded edge shall be heat sealed without collapse.

3. The graphic printing is clear and complete, no obvious bars are allowed, the mesh is clear and uniform, and the finished product is neat, without deformity and obvious deformation.

Health indicators
The hygienic index of the inner layer material of the composite tank that directly contacts food shall meet the requirements of relevant national standards.

Test method
Standard environment for sample condition adjustment and test
The standard environmental conditions for sample condition adjustment and test are 23 ℃ ± 2 ℃; The relative humidity is 50% ± 5%, and the sample pretreatment time is more than 24h.

Size and deviation
Without applying any external force, use a measuring tool with an accuracy of not less than 0.1 mm to detect the outer height and inner diameter of the composite tank (that is, the seal is straight
Diameter), when measuring the inner diameter, avoid the tank wall folding heat sealing structure, and there are 3 samples.

Release force of end cover
The outer diameter is 0.1 mm smaller than the inner diameter of the composite tank to be tested. It has a gas path and is equipped with a throttling valve
One annular clamping device;
0 kPa ~250 Ka, a pressure gauge of level 1.6; d) Safety cover

Testing procedure
Put the sample with a metal cover sealed at one end and no end cover sealed at the other end on the mandrel, and the distance between the mandrel and the end cap should not be less than the tank height
And clamp it with a ring device to install the safety cover.
Start the control valve to guide the compressed air into the composite tank through the mandrel, and increase the pressure within 6S ± 2S until it is blown off

Rapid leak test (air pressure method)

For the sample with single-end sealing, insert the gas guide sealing device into the unsealed end of the sample and tighten it; For sealed at both ends

For the sample, use a tool that can open a suitable air guide hole on one side of the tank cover without damaging the sealing part, insert the sealing device into the sample and tighten it Seal tightly.

Inflate the sample to make the pressure reach the specified pressure value.

After maintaining the pressure of the inflated tank for 60 s, completely immerse it in the water tank filled with water, rotate it for one week, and observe whether there are bubbles continuously

You can also use the negative pressure sealing test instrument, fill the sealing tester with water, put the paper cans sealed at both ends into the tester, empty the air outside the packaging area, and use the internal pressure of the product to observe whether there are bubbles overflowing in the water.
