Industry Application

Tea Blenders and Contract Packers

Sengong provides automatic vertical packaging machinery for tea blenders and contract packers who need to move from hand filling or outsourced packing to in-house production. The machines handle loose leaf, herbal, health care, rose, ginseng, and other local Chinese tea blends using nylon and non-woven filter films imported from Japan, plus biodegradable PET and PLA materials. Built for consistent output and food-safe packaging, they support high-volume, short-batch operations with minimal waste and operator input.

Pain Points We Hear

  • Hand filling leads to inconsistent bag weight and high labor costs
  • Outsourced packing limits control over quality, timing, and cost
  • Flat bag machines cannot handle coarse whole leaf or flower blends without jamming
  • Heat sealing damages delicate nylon film and creates wide waste edges
  • Non-food-grade materials risk failing safety audits or customer compliance checks
  • Lack of automation slows down short batch runs for multiple tea blends

What Buyers Need

  • A machine that runs whole leaf, flower, and root blends without jamming
  • Consistent fill weight across batches with 0.1 g accuracy per bag
  • Food-grade packaging materials that meet safety standards
  • A sealing method that avoids heat, glue, or wide waste edges
  • Quick changeover between bag formats and tea types
  • Certified machinery with reliable after-sales support
