Each batch of raw materials will provide a product raw material inspection report, so that the quality can be truly grasped from the source.

Compatibility test
Pesticide heat storage experiment (54°, 14 days), weightlessness, discoloration, appearance deformation, recommend the best bottles and caps (polyester bottles, barrier bottles, PE bottles)
Production testing
Testing according to product standards: air leakage experiments such as appearance, weight, wall thickness of barrier layer, etc., with side drainers (export products, per bottle)
Physical experiment
Conduct experiments in accordance with UN test standards
Freezer: (-18°, 3 days)
Drop test: 1.8M (within 3 minutes after freezing)
Stacking test: 40°, 28 days
Drop test: 1.8M (within 3 minutes after freezing)
Stacking test: 40°, 28 days

Basic performance	meaning	Identification method
Chemical stability： Does not react physically and chemically with pesticides	Ensure pesticide quality	Heat storage at 54℃: 4~5 days to see the preliminary results, 14 days to see the conclusions, weightlessness ≤1.5%
Internal and external barriers： The inner barrier prevents pesticide from seeping out, and the outer barrier prevents moisture from seeping in.	Ensure quality	Heat storage at 54℃: 4~5 days to see the preliminary results, 14 days to see the conclusions, weightlessness ≤1.5%
Not damaged： Drop, compression and stress are not broken	Economic and social benefits	-18℃/24H, 0.8-1.8meters drop does not break, 3 meters high stacking at 40 degrees, does not break for 28 days, PE bottled 7% surfactant aqueous solvent, 60 degrees 72H stress cracking the number of samples is less than the number of experimental samples put into 50%
No leakage： Inverted, hydraulic pressure and air pressure do not leak	Economic and social benefits	Inverted/flat, no leakage; capacity≥1L, small mouth leakage 100~250kPa, no leakage; capacity≥1L, small mouth 20~30kPa, no leakage
