Printed PE packaging bags are packaging made of PE as the base material and printed with graphics and text via professional processes. Their core advantages are as follows: Compared with ordinary low-quality printed packaging, their printing clarity is increased by 60%-80%, their smudge-resistant performance is enhanced, and the ink fading rate during transportation is reduced by more than 90%; Combined with the characteristics of PE material, their moisture resistance is increased by 30%-50% compared with non-PE printed bags, and their puncture resistance is increased by 25%-40%, making them suitable for use in multiple scenarios; For bulk customization, the comprehensive cost is 15%-30% lower than that of printed packaging such as aluminum foil and paper-plastic composite; For styles with brand graphics and text, the brand recognition is 50%-70% higher than that of non-printed PE bags, which can drive an increase in product repurchase rate by 20%-35%. They are widely applicable to fields such as food, daily chemicals, and industry.
