3.1 Classification
Industrial explosive packaging is divided into two categories: inner packaging and outer packaging according to the packaging level. Except for the outermost packaging (i.e. packaging container), which is the outer packaging, the rest are all inner packaging.
3.2 Packaging formwww.bzxz.net
3.2.1 Inner packaging form
According to the characteristics of industrial explosives and different usage needs, the inner packaging includes roll, middle bag and lining bag packaging. 3.2.2 Outer packaging form
According to the performance and transportation requirements of industrial explosives, the outer packaging may be in the form of bags, boxes, barrels, etc. State Bureau of Technical Supervision approved the implementation on 1994-03-01 on 1993-06-19
4 Packaging technical requirements
4.1: Inner packaging
4.1.1 Inner packaging materials
GB14493—93
According to the type of industrial explosives, choose materials with good moisture resistance, good compatibility with explosives, and economical and reasonable materials. Such as explosive roll paper, paper bag paper, polyethylene blown film for packaging (hereinafter referred to as blown film), etc. The inner packaging materials should comply with the requirements in the following table: Material name
Explosive roll paper
Paper bag paper
Blow molding film
Standard number
QB362||tt ||GB7968
GB4456
Material name
Plastic woven bag
Paraffin
Note: On the premise of meeting the requirements, other properties with better performance are allowed inner packaging materials. 4.1.2 Inner packaging methods and requirements
4.1.2.1. Medicine roll packaging
Medicine rolls are packaged in paper tubes, composite plastic films, blown film tubes or plastic tubes. Standard No.
GB8946
GB254
The paper tube is made of explosive paper soaked in paraffin and rolled according to certain size requirements. The tube wall should be no less than two layers. No wrinkles or wrinkles are allowed. For damage and obvious warping, the end of the medicine roll should be folded tightly from 3 to 4 sides and sealed tightly. If necessary, it should be sealed with moisture-proof agent. No accumulation of moisture-proof agent is allowed. Medicine: The amount of paper used in the roll and the amount of moisture-proofing should meet the requirements of specific product standards. After the composite plastic film and blown film tubes are packed into medicine rolls of certain specifications, they should be sealed tightly and the medicine rolls should be wiped clean. The plastic simple medicine roll is made of plastic simple medicine and then the barrel and the cover are integrated into one body, and the sealing is required to be tight. 4.1.2.2 Medium package packaging
Arrange a certain number of paper rolls neatly, wrap them with a layer of explosive paper, put them in a blown film bag, and evacuate and heat seal them to form a medium package. The heat-sealing seal of blown film bags should be in good condition without breaks or seams. Plastic cartridge rolls, composite plastic film cartridges, blown film cartridge rolls, and paper cartridge rolls with a diameter of 40 mm or more do not need to be packaged in intermediate packaging.
4.1.2.3 Liner bag packaging
Fixed weight bulk explosives are packed in large packaging bags composed of 2 to 3 layers of paper bags or one layer of blown film bags. When necessary, outer plastic woven bags, paper bags and blown film bags should be folded or tied layer by layer to prevent any medicine from being pinched or leaked. Pressed explosives, composite plastic film rolls, blown film cartridge rolls and paper rolls with a diameter of more than 40mm are directly put into blown film bags. If necessary, they are wrapped in plastic woven bags and folded and sealed. The size specifications of film bags and woven bags depend on actual needs. Simple medicine rolls in plastic tubes can be loaded directly into the outer packaging container. 4.2 Outer packaging

7.1 Static pressure resistance test of empty corrugated carton boxes
Place the empty box in the packaged state on a hard horizontal plane, and place a piece of paper that grows out of the top surface of the box at the center of the top of the box A loading plate with a surrounding area of ??not less than 100mm, and then place the weight as a load on the loading plane without causing impact, so that it is in uniform contact with the loading plane. The total weight of the weight and the plate is 3430±20N, and the center of gravity of the load is The distance above the loading plate shall not exceed 50% of the height of the box. Observe the deformation of the carton after withstanding pressure for 24 hours. 7.2 Folding endurance test of slotted carton
Open the empty carton, fold the carton flap inward 90° (in packaging state), and then fold it outward 90° once, repeat this 10 times, Measure and calculate the cumulative crack length on the inner and outer surfaces of the flexural line, and calculate the percentage of the crack length to the total length of the flexural line. 7.3 Water resistance test on the outer surface of the carton
Use a dropper to evenly drop 50 water droplets on the test surface of the empty box. The required water droplet size is 15 to 20 drops per milliliter, and no more than 10 drops per 10cm2 area. 2 drops. After 2 hours, absorb the water droplets with absorbent cotton or other materials. Observe whether there are traces of immersion on the surface of the test. The absorption rate is calculated as the percentage of immersed water droplets in all water droplets. 7.4 Determination of moisture content of carton board
Determination of moisture content of carton board shall be carried out in accordance with the provisions of GB462. 7.5 Medium package water immersion test
Medium package water immersion test shall be carried out in accordance with the regulations of GB12438. 7.6 Determination of moisture content of wooden box boards
