Case Background
Customer Industry: Snack food manufacturing, mainly updating the packaging of a cookie this time.
Customer Pain Points: The original rolled film had insufficient barrier properties, leading to moisture and oxidation of the snacks, and the shelf life was shortened to 2 days;
Printing patterns were prone to fading, affecting the brand’s visual appeal;
The precision of the rolled film cutting was poor, and the packaging machine frequently jam, resulting in low production efficiency.
Partners: Hengtai Packaging (Professional soft packaging solution provider)
Customized Demand Analysis
Functional Requirements:Barrier performance: Need to block oxygen and water vapor, extending the shelf life to 45 days;
Printing quality: High clarity and abrasion resistance are required and the pattern color should remain bright and vivid for a long time;
Mechanical properties: The tension of the rolled film should be uniform, and the cutting tolerance should be controlled ±0.3mm, suitable for high-speed packaging machines.
Cost and Efficiency:
The customer hopes that the unit price will be 8% lower than products in the market, while improving the efficiency of the packaging line;
The delivery cycle needs to be shortened to within 10 days to meet the demand in the peak season.
Environmental Protection and Compliance:
Comply with FDA food contact material standards, with no risk of harmful substance migration.
Hengtai Packaging's Solution
Material and Process Innovation:
Base material selection: Use biaxially stretched nylon (BOPA) film with a thickness of 15μm to enhance punct resistance;
Barrier layer design: Composite EVOH (ethylene-vinyl alcohol copolymer) barrier layer, reducing the oxygen permeability to 10/m²·24h;
Printing process: Use UV cured ink, certified by ISO 15378, pattern abrasion resistance increased by50%, color saturation reached 95%;
Slitting and matching optimization:
Introduce laser positioning slitting system, tolerance control within ±0.2mm packaging machine downtime rate reduced to 0.3 times/hour;
Provide rolled film tension test report to ensure compatibility with customer’s existing equipment.
Cost Control
Reduce material costs by 12% by purchasing EVOH raw materials on a large scale;
Optimize slitting process, scrap rate reduced to 2.%, saving about 800,000 yuan a year.
Cooperation Process and Results
Sample testing stage:
Hengtai Pack provided 3 formula samples, and the customer selected the final scheme through an accelerated aging test (stored for 45 days at 40℃, 75% RH
The printed pattern did not fall off after 8000 times of friction test, and passed the ASTM D5264 standard test.
Small batch production matching:
Produce 2000 rolls (each roll is 600 meters) for packaging machine matching test, and the production efficiency was increased by 2% after adjusting the tension parameters;
Customer feedback: “The precision of the rolled film cutting far exceeded expectations, the packaging machine ran stably, and the manual intervention was by 70%.”
Mass production and delivery:
Sign an annual framework agreement, deliver 8000 rolls stably every month, and the delivery was shortened to 8 days;
The customer’s peak season production capacity increased by 30% to meet the surge in orders.
Effect Evaluation and Customer
Performance improvement:
The oxygen permeability was reduced from 1200 cc/m²·24h to 8 cc/m²·24h and the water vapor permeability was reduced from 20 g/m²·24h to 3 g/m²·24h;
The abras resistance of the printed pattern reached grade 4.5 (highest 5), and the color retention rate was increased by 40%.
Economic benefits: The customer’s packaging cost was reduced by 18%, saving about 1.5 million yuan a year;
The product return rate was reduced from 3 to 0.5%, and the terminal sales increased by 15%.
