Price Adjustment Notification-OK Packaging

Dear Valued Customer,

Wesincerely appreciate your long-term support and partnership, which have fostered a solid and trusting relationship between our two companies.

Recently, due to international geopolitical conflicts and drastic changes in the global energy landscape, all our upstream chemical suppliers have issued price increase notices to us. The sharp fluctuations in international oil and natural gas prices, particularly the sustained rise in crude oil prices, have directly driven up the costs of raw materials including PET, CPP, PE, VMPET, and NY. At present, some of our products are being sold below production cost. We will keep you informed of any further upward or downwardcost movements based on actual market conditions.

Despite our ongoing efforts to mitigate cost pressures through inventory optimization and enhanced production efficiency, we are still unable to fully mitigate the impact of such severe market fluctuations. To ensure consistent product quality and reliable service, we have carefully assessed the situation and decided to implement corresponding adjustments to our product pricing.

As each customer’s requirements are customized, please consult our sales representatives for the specific adjusted pricing before placing new orders.

**Special Note**：Orders already confirmed or with finished inventory in stock will remain unchanged and unaffected.

We sincerely apologize for any inconvenience this adjustment may cause and greatly appreciate your understanding and support. We will continue to monitor market developments closely, provide you with more competitive products and services, face challenges together, stand with you through difficult times, and look forward to maintaining long-term cooperation and mutual growth.

Hereby formally notified.
Best regards for your business success.
