Packing: packed in bags order process first, after clinch a deal with the customer, custom bags need to make the following process: 1: good design specification, material, thickness and package type, and based on these data to the design draft packing bags of the designer or manufacturer, can design a few more, design to give some reference and ultimately determine the bag.
Especially when the design should pay attention to the words on the packet information, pay attention to the following content: packaging manufacturer name, ingredients such as iron, calcium sodium, etc. , product introduction, origin, turnning is mainly a g/kg, specifications, food labels, QS certification, hygiene license number, production date, storage conditions and shelf life, food use method, name of manufacturer, address and contact phone number, including QS and barcode must not be less.
The second step: after the draft process of determining, need professional technicians to design color separation, do repair for some not clear place, at the same time also need a dozen process to complete the process, here not introduce one by one, if you need to understand the details can be seen.
Step 3: after the printing materials to prepare using high-speed presses will be printing surface membrane (
When printing each color has a plate roll, plate rolling is carved intaglio engraving)
, when the printing ink is continuously flowing, because the ink condenses, during the printing ink printing and membrane with a scraper, scraper is on board scrape ink roll out, such a hollow plate rolling can be printed.
If the blade is stained with dirt on strips of ink pollution phenomenon will occur.
Because ink for dot ink pollution phenomena in rolling printing ink splashed onto the packaging film and cause the dot of ink pollution.
Step 4: compound after the printing surface membrane and easy to heat sealing layer of film with special glue dedicated high-speed peritoneal machine for composite.
Step 5: after the curing compound need to be more than 45 degrees curing chamber for 24 hours aging, in order to make
food packaging is not easy to take off a layer.
Step 6: bag packing bags of food production at this time have been coming to an end, bag making technician is the need to have certain skills, must ensure that the color bags not leak sealing side is good, the temperature control of the hot knife has certain technical.
After the qc inspectors inspection factory.
Step 7: quality bags main test items: size (long
mm）
, wide (
mm）
, thick (
嗯)
, appearance, overprint error, off color, peel strength, heat sealing strength.
1, long, wide USES is ruler for testing, testing using the thickness gauge, thickness detection method are the same as we test.
2, to examine the color difference, the main is through the sealed samples with the standard check, at arm distance color difference should be consistent.
In terms of color in the printing factory also through a magnifying glass to 50 times to check the print color, color is general by a branch of a combination, if the wrong color so outlets will be irregular distribution.
Are the rules of the general branch and branch are round 3, to overprint error checking is mainly visual presence of the phenomenon of double printing.
4, peel strength and heat sealing strength mainly adopts AGS -
5 KNG electronic universal testing machine for testing.
, the principle of detection is the same with our computer tension meter.
Peel strength test is mainly to bags with the blade cut into the packing bag of 15 mm basket, a packet with the blade after its crumpled artificial stratification, the stratification of the bags on the tension meter on both sides of the side clips a piece and then can use a computer tension meter.
To test the peel strength.
5, the manufacturer also can detect oxygen transmission rate of the packaging bags, detection instrument is MT -
C1 oxygen transmission rate that is constant temperature type gas test device.
Step 8: put in storage for the packing bag of quality inspection qualified, good for packaging, at the same time into the unified management of warehouse, so that the late delivery is convenient.
Step 9: the shipment packaging warehousing, customer contact, according to the near and far, far logistics, close to delivery.
Far logistics distribution (
Ensure no damage to the goods)
, close to free delivery to the door.
