This standard specifies the analysis method of the hygienic index of polyvinyl chloride molded products for food packaging. This standard is applicable to the analysis of the hygienic index of molded products such as sealing gaskets for beverage bottles, which are made of polyvinyl chloride resin for food packaging as the main raw material, according to a specific formula, and processed by calendering or blow molding with non-toxic or low-toxic plasticizers, stabilizers and other additives, and are used for packaging of various candies, cakes, biscuits, stewed food, pickles, cold drinks, condiments and other foods.

Analysis method of hygienic standard for polyvinyl chloride molding products for food packaging
This standard defines the analysis method of chlorine-free packaging products and indicators. GB/T5099.67-2003
This standard applies to food packaging Polyethylene is a raw material of three evils. According to the specific formula, it is free of or has low plasticizers, injection molding agents, etc. It is used in various protective equipment, machine tools, cakes, food, cold drinks, condiments, etc. The analysis of the hygienic indicators of the whole sealing and molding stations: 2 Normative references || tt || The following documents become the clauses of this standard through reference to the standard. All documents with the date of reference are used in the following order! The latest versions of these documents without the date of reference are not applicable to this standard. 3. Polyethylene and polystyrene for food packaging 1. The color of the product is clean and positive, without foreign matter, and it meets the requirements of the product 1. 2. The same batch of products is the same material and the same specification batch. Take 1 piece from each batch (5 pieces: when the piece is less than 5 pieces/piece, the test column should be 1m or 2.5m long, and indicate the product name, batch number, and sample collection month. The sample should be kept for two months in preparation for the standard. 5. Sample treatment
5.1 Sample treatment: rinse the sample with a tap water, rinse it with water, and then use it. 5.2 Soaking: Soak the sample Calculate the foam limit based on 2.*L per square meter of sample: 5.2.1 Water 0T, soak for 0.5h.
5.2.2 Acetic acid (4%\.50. Calibration pool\.h
5.2.3 Ethanol (2%) 501, foaming 0.h.
5.2.4 Temperature: soak for 3.5h,
G Vinyl chloride monomer
6.1 Source treatment
According to the relevant laws of gas companions. Put the sample into a sealed bottle, use a squeezer to dissolve it, and bake it at a certain temperature to reach the balance of the two gases injected into the gas spectrum test. This formula reaches a low particle limit of 3.2mg/kg
: This formula can be used to test the activity of rat ethylene,

6.2 Test report
6.2.1 Ethylene: 2-99.5 mL, placed in a 10 mL-100 mL container and placed in a warm place. 6.2.2 N,N-dimethylformamide (DM4) Under similar chromatographic conditions, this decomposition agent should not produce any peak with the same retention value as ethylene oxide. Otherwise, the gas will be disturbed by the flame, E.2.3 Preparation of ethylene standard solution A: Collect a balance, add 24.5 ml DM1A, and weigh with a stopper (accurate to 3.5 mT). In the extended air, add about 0.5 m of vinyl chloride to form vinyl ammonia. After the energy is released, weigh it again and calculate the concentration according to the formula (1):
V=24.5,m-
Wherein,
-vinyl added monomer liquid concentration, the unit is m/s; Ca:
V——corrected volume. The unit is liter (1 ml). The mass of the flask added, the unit is gram (g).
The mass of ethylene oxide in a state, unit is gram (relative density of vinyl chloride, $15m20/2℃%. 1: For the chemical test, the true volume of ethylene oxide is calculated. 2
Product. 2.4 Use the preparation of commercial B to prepare 2=.0mL of quick-prepared A solution in a balanced bottle, and calculate the concentration of the ethylene oxide standard wave 3 of 2mg/mL by adding solvent. Then use formula 3) (4) to calculate rV = 23-V
