Polycarbonate (PC) greenhouse greenhouse structures mostly use double-layer transparent sheets. If this double-layer transparent sheet is used, it is lightweight and importantly, has strong light transmission, which is beneficial for plant growth. Importantly, it ensures there are no sun dead zones inside the greenhouse, improving land utilization and light transmission performance. Importantly, the transparency does not significantly degrade over time. PC is a thermoplastic with excellent impact resistance, meaning it maintains minimal potential for deformation and stress even at high temperatures. Sheets made from PO also have good impact resistance and can maintain stable performance over a wide temperature range (-40~+120°C).
