I. The Client’s “Freshness” Challenge in the Supply Chain (Trust & Authority)
Client Background:
A famous bakery producer in Guangzhou, China, makes popular products such as mochi and serves big supermarket chains.
Core Challenge:
The client works on a rigid, same-day fresh production system. All products have to be produced, packed and dispatched in a single day. This implies that the line should be based on highly stable and fast equipment. Their desired production was 6,000 boxes per hour (approximately 50 packs/minute), which would need a high-speed shrink wrap machine for food to operate continuously.
Initial Bottleneck:
Before 2021, they used a conventional L-bar sealer, which only made 20 packs per minute. This significant difference in demand (50 packs/min) and actual output resulted in critical delays in the supply chain, as well as excessive labor requirements and increased turnover expenses.
II. Professional Solution of Tengyi: Servo Technology Upgrade & Performance Reinvention (Expertise & Experience)
Core of the Technical Upgrade:
Tengyi supplied the high-speed servo driven vertical L-bar sealer TY-5545CZ to bridge the performance gap: it is a fully automated-packed solution with Panasonic servo control technology, rather than the conventional pneumatic system. This modification helped to increase the speed, enhance the consistency of sealing, and make the work stable.
EEAT Optimization: How Servo Addresses Critical Pain Points
1. Precision & Stability:
The servo system provides precise temperature regulation as well as consistent film tension, so that even at high-speed, all seal lines are clean, solid, and smooth. The change in bag size remains at 5mm with a 98% yield rate, which is a major requirement in bakery packaging.
2. Maintenance & Reliability:
TY-5545CZ is among the most developed models of Tengyi capable of producing 24 hours. It is easy to maintain: periodically change Teflon tape on the sealing knife and eliminate the residue of the shrink-film, as necessary. This maintains the long-term performance without rising operating costs.
III. Quantified Results & ROI Verification (Authority & Trust)
| Performance Metric | Before Upgrade (Traditional L-Sealer) | After Upgrade (Tengyi Servo L-Sealer) | ROI |
| Single machine speed | 20 packs/min | 50 packs/min | 1.5× increase |
| Packaging yield | 80% | 98% | 18% fewer defects |
| Strategic additional purchase | N/A | 8 new units added in 2025 | Proven scalability & trust |

IV. Client Value & Strategic Partnership (Client Value and Authority)
Three Core Values Tengyi Servo Solution delivers
1. Massive Boost in Output, No More Shipping Delays:
The speed of production boosted by 150% and 6,000 boxes per hour can now be packed and shipped as scheduled. This completely eliminated their longstanding bottleneck of “freshness” and stabilized their same-day delivery model.
2. Stable Operation, Controlled Costs:
The machine has served a term of five years. The energy usage is 10-20% less than conventional pneumatic L-sealers since the TY-5545CZ is based on the principle that it does not require an air compressor, and thus, the overall energy consumption decreases, and performance is enhanced.
Total Cost of Ownership (TCO) is further reduced by the increased life of components, like Teflon tape on sealing blades.
3. Strategic Trust, Market Validation:
In 2025, the client ordered another batch of eight machines, which is a good indication of confidence in the quality of equipment provided by Tengyi and its ROI performance. This cemented Tengyi’s reputation as a reliable vendor of scalable shrink wrap machine for food to high-demand production facilities.
Tengyi’s Conclusion:
The high-speed servo driven vertical L-bar sealer is far more than an equipment upgrade; it is a strategic production device that will enable the clients to scale the output, and enhance their supply chains. Having a stable field performance and data-supported results over five years, Tengyi is still providing reliable solutions in high-demand shrink wrap machine for food applications.
