Drawing on years of experience serving agricultural film customers, we have identified several common pitfalls when purchasing PO film:

Focus only on thickness, ignore formulation: Even with the same thickness, different ratios of anti-aging additives and anti-dripping agents can result in significantly different actual service lives.

Neglect ultraviolet intensity: In regions with strong UV radiation, standard films are prone to premature aging and cracking; choose products with an appropriate weathering grade.

Blindly pursue low prices: PO film offered at excessively low prices may cut corners on raw materials, leading to issues like loss of anti-dripping performance and reduced light transmission after just six months to a year of use.

Ignore installation method: PO film has specific requirements for tensile force and fixing methods; improper installation can affect performance and lifespan.

Fail to confirm available stock: Agricultural seasons in Yunnan are concentrated; if the supplier lacks ready stock, it may delay the timing for covering crops.
