Kraft Paper Tea Boxes printing and packaging knowledge of the carton industry standard

National Entry-Exit Inspection and Quarantine Bureau is the administrative department responsible for the inspection and check of import and export commodities in our foreign trade system, which also includes the quality control of export cartons. This department has its own inspection standard (inspection and quarantine standard), including the inspection standard for cartons. Different from national standard is, national standard includes cover our country to carton this packaging form of all commonality detection methods and technical standards, inspection and quarantine standards aimed at exporting carton this individual field, has its particularity, describe more detailed. So to understand these standards for carton manufacturers, its necessity is obvious.

With the more and more extensive use of cartons, the detection of various performance of cartons has become more important. The detection of paper products and cartons mainly includes the following types:

1. The national standard of corrugated carton is GB6553-2008, and its main test items include carton compression and stacking strength test.

2, the national standard GB/T13024-2003, the main test items include ordinary box cardboard, cowskin hanging box cardboard and cowskin box cardboard quantitative, thickness, tightness, breaking index, transverse ring pressure index, transverse bending resistance, water absorption, moisture and so on.

3, the national standard GB/T6544-2008 mainly on the thickness of corrugated cardboard, side pressure strength, bonding strength, breaking strength, puncture strength and water test items made specific provisions.

4. The national standard is GB/T13023-2008, mainly testing whether the quantitative, tightness, transverse annular compressive strength index, longitudinal crack length and moisture of corrugated base paper meet the relevant standard requirements.

5, GB/T451.2-2002 "Quantitative determination of paper and board"), wherein quantitative is one of the most basic performance indicators of paper, quantitative is often regarded as the characteristic parameters of paper. The so-called quantitative is "according to the prescribed test method to determine the mass of paper and board per unit area, unit is g/m2." The accuracy of paper quantitative measurement is related to the area accuracy of the tested sample and the accuracy of the weighing device. It is suggested to use the stamped circular quantitative sampler and the balance with the precision of 0.01g for weighing.
