In the wave of packaging upgrading in the food and beverage industry, pain points such as "difficult to tear and easy to leak" milk tea cup film, "sealing and easy to open contradiction" of yogurt cup film, and "difficult to open and break" of can pull tab have long plagued enterprises. Taichang Instruments is deeply involved in the field of packaging testing and has launched the TC-KL series opening force tester, which targets core requirements with high-precision measurement and control technology. It provides a full process solution from research and development to mass production for three major scenarios, promoting the industry's transformation from "experience production" to "data-driven".

1、 Milk tea cup film: precise measurement and control of balancing ease of tearing and sealing

core pain point

750 After the popularization of large-sized milk tea cups such as milliliter deep cups, the problem of uneven heat sealing strength of cup film has become prominent——Tight heat sealing can prevent consumers from tearing it off, while loose sealing can cause transportation leakage; The contradiction between serrated design and material properties further exacerbates the difference in opening experience.

Taichang Technology Solution

•Customized cup film testing fixture: adapted to different cup mouth shapes such as circular and square, simulating real opening angles（15°-90°Adjustable), precise capture“Breaking Power-Continuous opening force”Full curve;

•High precision data collection: using0.1NPrecision sensors and2000 time/Second reading rate, synchronous detection of heat seal strength and tear resistance, matchingGB/T 15171Sealing performance standards for flexible packaging;

•Intelligent data analysis: Built in milk tea cup film exclusive parameter library, automatically identifying the critical point of cohesion and peeling of heat sealing layer, avoiding “Tear the cup body”“Membrane fracture”Waiting for non compliant situations.

Industry influence

•After the application of a certain top milk tea brand, the opening force of the cup film is controlled within8-15NComfort zone, consumer“Difficult to tear”Complaints decrease68%The leakage rate during transportation3.2%drop to0.5%；

•Assist enterprises in optimizing heat sealing temperature parameters and improving production efficiency12%Reduce the loss of raw materials23%.

2、 Yogurt cup film: dual protection of sealing and easy opening in low-temperature scenarios

core pain point

Yogurt cup film needs to meet both requirements “Low temperature storage, sealed and leak proof”and“Convenience of opening at room temperature”The blending characteristics of heat sealing layer materials result in significant fluctuations in opening force; The change in membrane strength after pasteurization further increases the difficulty of quality control.

Taichang Technology Solution

•Low temperature environment adaptation: support0-40℃Temperature and humidity controllable testing, simulating the opening state of cup film after refrigerated storage, accurately measuring the breaking force and heat sealing layer peeling force;

•Multi dimensional parameter synchronization: integrated sealing performance and opening force dual detection module, completed in one test “Opening force-leakage rate”Association analysis, direct data integration with enterprisesERPSystem;

•Cohesive peeling special test: for yogurt cup film “Cohesive peeling”Design requirements, precise positioning of heat sealing layermost suitableFusion point to avoid membrane tearing or cup damage.

Industry influence

•A certain dairy product enterprise optimized the heat sealing process through Taichang Instrument, and the qualified rate of yogurt cup film opening force increased from82%upgrade to99.3%Improving consumer satisfaction51%；

•comply withGB/T 15171Sealing standards and food safety compliance requirements help enterprises passGMPCertification on-site audit.

3、 Easy to pull canspull tabCracking the Contradiction between Open Experience and Structural Security

core pain point

canpull tabexist “Difficulty in opening”“Ring breakage”“Splashing and leaking liquid”The three major issues are the difference in the force arm design between the external lifting and embedded pull rings, which makes it difficult to control the consistency of the opening force;pull tabThe balance between fatigue life and opening force has become a core challenge for enterprise research and development.

Taichang Technology Solution

•pull tabSpecial testing module: simulating lever principle testing, accurately measuring the opening force, continuous opening force, and torque value of the pull ring, capturingpull tabInstantly initiate a sudden change in force value (reading rate reaches) 5000 time/Seconds);
