How to self-help cigarette pack printing enterprises under double pressure

BAIDU_CLB_fillSlot("858283");

In September 2016, the official implementation of YQ 69-2015 "Safety and Hygienic Requirements for Cigarette Strips and Box Packaging Papers" (hereinafter referred to as "YQ 69-2015 Standards") raised the safety standards for cigarette package printing to a new level. In order to improve environmental quality, the national environmental protection department and local governments at all levels have implemented strict VOCs sewage charges policies for pilot industries including printing companies.

Then, how does the cigarette pack printing enterprise break through the self-rescue? The author believes that, on the one hand, according to the YQ 69-2015 standard and YC 263-2008 "Limited Volatile Organic Compounds in Cigarette Strips and Box Packaging Papers" (hereinafter referred to as The different requirements of the “YC 263-2008 Standard” and the company's own situation to develop countermeasures.

On the other hand, to find the commonality between the internal safety and health requirements of cigarette packages and the compliance of VOCs, the environmental quality compliance requirements should be comprehensively considered on the basis of eliminating the risk of excessive safety and health indicators of cigarette packages.

Targeted to develop clear response measures

YC 263-2008 standard

And the characteristics of local tobacco companies

01

The YC 263-2008 standard only limits the content of VOCs in the finished products of cigarette packets. There are only 16 kinds of compound components, and the other components except benzene adopt the method of comprehensive judgment of exceeding the standard ratio. For the common solvent, the single component exceeds the standard, and the cigarette package printing enterprise is in the process of implementation. It has a high degree of flexibility, and can reasonably match the solvent used for printing according to the respective process characteristics of the company.

02

In the later period, the National Tobacco Quality Supervision and Inspection Center increased the standard solution composition from 16 to 21, and then increased to the current 25, but the YC 263-2008 standard has not changed (ie, there is no limit requirement for increasing ingredients). .

According to the product characteristics of their respective companies and the YC 263-2008 standard, local tobacco companies have formulated more stringent corporate standards, such as the addition of limited components of volatile organic compounds; some have changed


The sum of the over-standard ratios (from 15 in the YC 263-2008 standard to 12 or lower); some of the commonly used solvent limit indicators are properly amplified, taking a single-item method... but no matter how it is adjusted, the test items are mostly limited to volatilization. Sexual organic compounds, the difficulty of reaching the standard is not too big.

YQ 69-2015

Standard features

1

In addition to the solvent residue (ie, volatile organic compounds in the YC 263-2008 standard), the YQ 69-2015 standard also adds formaldehyde, total phthalate (box packaging paper only), specific aromatic amines. Total amount (box-wrapped paper only), photoinitiator (box-wrapped paper only), total amount of diisopropylnaphthalene (box-wrapped paper), 5 types of chemical testing items, and D65 fluorescence brightness (box only) Wrapping paper) 1 physical index (original YC/T 330-2009 "Cotton Strip and Box Packaging Paper Print" fluorescent substance <254 ~ 365nm>, YC / T 330-2014 "cigarette strip and box packaging paper print" Also changed to D65 fluorescence brightness; this project is not difficult to achieve the standard, not to repeat below.

2

The specific volatile organic compound names are not listed in the YQ 69-2015 standard, and the limit requirement for ethanol is released, that is, there is no limit requirement for any compound (except benzene), and only the total solvent residue is limited to ≤100 mg. /m2.

The total amount of solvent impurities is limited to ≤10mg/m2 (the standard stipulates the 12 substances specified in YQ 15.4 "List of permitted substances for tobacco materials, part 4: frame paper, cigarette wrapping paper (bars and boxes) and seal paper": Ethanol, n-propanol, isopropanol, ethyl acetate, n-propyl acetate, isopropyl acetate, propylene glycol methyl ether, propylene glycol ethyl ether, dimethyl succinate, dimethyl glutarate, dimethyl dicarboxylate Except for ester and 2-butanone, the remaining components are solvent impurities).

Benzene series ≤1.0mg/m2 (ie, the original YC 263-2008 standard toluene, ethylbenzene, xylene, and the content of the sum of the three, the risk of exceeding the standard is not large); limited benzene ≤ 0.02mg / m2 (former YC In the 263-2008 standard, the limit is 0.01 mg/m2, and the YQ 69-2015 standard requires relaxation. However, the total solvent residue includes the solvent impurity limit, and the total amount of solvent impurities includes the benzene and benzene series limits.

Although the YQ 69-2015 standard has added five major types of chemical testing projects, the risk of exceeding the standard is small from the monitoring data of our company in 2016 (except for external inspections other than formaldehyde) and the external communication in the industry. For the gravure large series of cigarette packets, which are still based on ordinary solvent inks, the risk of solvent residue exceeding the standard is still very large, and the risk of solvent impurities exceeding the standard exists at the same time.

YQ 69-2015 standard involves projects

Detection and monitoring and risk response measures

solvent remains

Solvent residue indicator monitoring and risk elimination

1 Purchase gas chromatography-mass spectrometer to meet the requirements of current standards for hardware facilities

2 gravure ink based on ester-soluble solvent ink should be converted into ink system as soon as possible

3 Pay attention to the risk of solvent impurities exceeding the standard, and pay close attention to the risk of solvent impurities exceeding the standard.

Project indicator monitoring

The chemical detection items of the five major categories of formaldehyde, phthalate, total aromatic amines, photoinitiators, and diisopropylnaphthalene are relatively low in risk, and there are many special equipments required for testing. The operation is complicated, the inspection procedure is cumbersome, and the professional qualification of the inspection personnel is relatively high. Therefore, it is recommended that the cigarette package printing enterprise adopts the method of entrusting external inspection on a regular basis (March/time, half year/time or one year/time).

For cigarette printing enterprises with more offset printing products, especially laser paper and transfer paper as the main printing materials, enterprises with UV printing, wrinkles and other screen printing products on the surface may consider purchasing equipment and triggering on light. The agent is self-checked. Of course, for printing companies with strong capital and high product structure, it is necessary to have relevant testing equipment and human resources to realize self-inspection and self-control of all safety and health indicators of cigarette packages.

Supplier management

Do a good job in supplier management to ensure the safety and health indicators of raw and auxiliary materials are in conformity.

Putting pressure on suppliers to allow suppliers to make safety and hygiene standards for raw and auxiliary materials is still a forward-looking measure to ensure the quality and safety of cigarette packages.

In short, cigarette pack printing enterprises must achieve the product quality and safety and VOCs emission standards at the same time, first, to configure professional testing equipment and testing personnel; second, the gravure printing process to convert the ink system; third, to purchase VOCs governance system, from many aspects Start with comprehensive consideration and orderly implementation of rectification and governance. Although the road ahead is very difficult, we still have to strengthen our convictions and hopes, set off our sleeves and work hard, and open our arms to create a better tomorrow.
