Raw Material Inspection

Raw Material Inspection

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

Product Performance Testing

  • 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

    dian Freezer: (-18°, 3 days)

    dian Drop test: 1.8M (within 3 minutes after freezing)

Basic performancemeaningIdentification method

Chemical stability:

Does not react physically and chemically with pesticides

Ensure pesticide qualityHeat 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 qualityHeat 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 benefitsInverted/flat, no leakage; capacity≥1L, small mouth leakage 100~250kPa, no leakage; capacity≥1L, small mouth 20~30kPa, no leakage
