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, biohajoava
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), vaatimukset paperiputken tiivistyskyvylle eivät ole kovin korkeat. Se voi läpäistä normaalin kuljetus- ja pudotustestin.
2. Paperipurkkipakkaus suoraan kosketukseen elintarvikkeiden kanssa
Ruoan on oltava suorassa kosketuksessa paperiputken sisäseinän kanssa, paitsi että tuotantoympäristö ja materiaalit saavuttavat elintarvikeluokan. Kiinteyttä, kireys, ja paperiputken kosteudenkestävyys sulkemisen jälkeen ovat tärkeitä teknisiä standardeja.
Yleensä, yläosa on tiivistetty helposti repäistävällä kannella tai helposti vedettävillä kansilla, 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
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
It 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 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
Appearance
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, työnnä kaasuohjaimen tiivistyslaite näytteen tiivistämättömään päähän ja kiristä se; Molemmista päistä tiivistetylle
Näytteen vuoksi, käytä työkalua, joka voi avata sopivan ilmanohjainreiän säiliön kannen toiselle puolelle vahingoittamatta tiivisteosaa, aseta tiiviste näytteeseen ja kiristä se Tiivistä tiukasti.
Täytä näyte niin, että paine saavuttaa määritellyn painearvon.
Kun täytetyn säiliön paine on ylläpidetty 60 s, upota se kokonaan vedellä täytettyyn vesisäiliöön, 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.
