Speaking of packaging film performance, the first to introduce to you under the packaging film. Packaging films mainly by the work of several different grades of polyethylene extrusion from allyl resin mixture, puncture resistant, super-strength high-performance, stacked on pallets of goods on the wrapped package, to make the packaging more stable and clean, even with ultra-strong waterproof function, then the performance of the packaging film to be a simple introduction.

 According to the bouncing ball manufacturers aware of packaging film with solubility, dissolution can only come through the Rare aniline point indicated. Different levels of oil to add agents to the compound solubility limit aniline point is different, low-ash oil is too alkaline oil limits larger than single-grade oil limits larger than the multi-grade oil. The second is anti-rust performance, which refers specifically to anti-rust oil should possess special physical and chemical properties, its experimental approach includes wet experiments, salt spray, lamination experiment, water displacement experiments, in addition to thermometer screen test, temporary storage of the three experiments with special physical and chemical properties of smooth fat. In addition to individual physical and chemical properties of smooth fat, the special use of fat as well as its special physical and chemical properties. Packaging film, such as smooth and good waterproof grease request washout experiments; low fat to low-temperature torque measurements; multi-effect smooth anti-wear extreme pressure to measure fat and rust. The last one is the electrical properties: the electrical properties of insulating oil is a unique performance, it is important for media loss angle, dielectric constant, breakdown voltage, pulse voltage. Tianjin oil refining basic packaging film depth, impurities, water and so on the electrical properties of the oil have a greater impact.
