Headline: Precision Technology Cuts Material Waste by 79%, Saving $126,000 Annually for Malaysian Packaging Manufacturer

Material waste is the single largest hidden cost in blown film production, eating into profit margins and undermining sustainability goals. For many manufacturers, waste rates of 8-15% are considered "normal"—but they don't have to be.
In this case study, we share how Hebei Chengheng's advanced precision technology helped a leading Malaysian packaging company slash their material waste from 12% to just 2.5%, delivering immediate and dramatic improvements to their bottom line while reducing their environmental footprint.

Customer Background

Company: Kuala Lumpur Packaging Sdn Bhd
Location: Kuala Lumpur, Malaysia
Business: Manufacturer of shopping bags, courier bags and food packaging films
Production Capacity: 220 tons/month
Previous Equipment: 2 units of 10-year-old single-layer blown film machines
Before partnering with Hebei Chengheng, the company was struggling with persistently high material waste that was eroding their competitiveness in an increasingly price-sensitive market.

The Challenge: Sky-High Material Waste Eating Into Profits

The company's outdated equipment was causing multiple waste-related problems that cost them over $140,000 annually:
  • Average material waste rate of 12%: 26.4 tons of plastic resin wasted every month
  • Inconsistent film thickness: Thickness deviations of up to ±15% led to frequent production rejects
  • Manual feeding errors: Volumetric feeding systems caused inconsistent material ratios and quality issues
  • Long changeover times: Product transitions generated 50-80 kg of scrap material each time
  • Excessive edge trim: Poor bubble stability resulted in wider edge trim than necessary
"Material costs account for 70% of our total production expenses," said Lim Wei Ling, Operations Manager at Kuala Lumpur Packaging. "At 12% waste, we were literally throwing away tens of thousands of dollars every month. We knew we needed to upgrade our equipment to stay competitive."

The Solution: Hebei Chengheng's Precision-Engineered Blown Film Line

After evaluating multiple suppliers, the company chose Hebei Chengheng's CH-3L-1600 Three-Layer Co-Extrusion Blown Film Machine equipped with our industry-leading waste-reduction technologies:

1. Difini Gravimetric Loss-in-Weight Feeding System

  • Replaced inaccurate volumetric feeders with precision gravimetric system
  • Material ratio accuracy of ±0.1% compared to ±5% with previous system
  • Eliminated batch-to-batch variations and reduced formulation-related waste

2. Automatic Thickness Control System

  • Real-time thickness measurement and automatic die gap adjustment
  • Maintains film thickness within ±3% tolerance across the entire width
  • Eliminates over-thickening that wastes material and increases production costs

3. K-design High-Efficiency Air Ring

  • Advanced aerodynamic design provides uniform cooling around the entire bubble
  • Improves bubble stability, reducing breaks and associated scrap
  • Allows narrower edge trim, cutting trim waste by 40%

4. PLC+HMI Intelligent Control System

  • Stores 100+ production recipes for one-click product changeovers
  • Reduces changeover time from 45 minutes to 12 minutes
  • Minimizes scrap generated during startup and transition periods

The Results: 79% Waste Reduction, $126,000 Annual Savings

Just three months after installing the Hebei Chengheng machine, the company achieved remarkable results:

Additional Benefits

  • Improved product quality: Consistent thickness and clarity allowed the company to enter the high-end food packaging market
  • Reduced labor costs: Automation reduced the number of operators required per shift from 3 to 1
  • Environmental benefits: 250 tons of plastic waste prevented annually, helping the company meet their sustainability targets
  • Faster ROI: The machine is on track to pay for itself in just 14 months

Customer Testimonial

"The results have exceeded all our expectations," said Lim Wei Ling. "We knew upgrading would reduce waste, but we never imagined we could get down to 2.5%. The Hebei Chengheng machine has completely transformed our production process.
The material savings alone will pay for the machine in just over a year, and that's not even counting the increased production and higher-value products we can now make. We're already planning to replace our second old machine with another Hebei Chengheng line later this year."
