To help customers better understand and select the tensile testing machine that best suits their needs, this article provides a systematic comparative analysis and purchasing guidance for Sunuo's entire range of plastic film tensile testing machines.

As the core quality control instrument for flexible packaging materials, plastic film tensile testing machines are widely used for mechanical property tests including tensile, peel, heat seal, tear, and puncture. Sunuo offers seven models: SN‑1E, SN‑1SE, SN‑2E, SN‑2SE, SN‑2CE, SN‑3E, and SN‑DE, covering a complete product matrix from economical to high-end, and from single-column to dual-column configurations.

Product Portfolio Overview

1. Positioning Summary

2. Applicable Industries

All seven models are suitable for packaging, food, pharmaceutical, new materials, chemical, and printing industries, but they differ in specific material testing scope and load capacity.

Detailed Parameter Comparison

1. Core Technical Parameters

Special note: SN‑1E and SN‑1SE are identical in measuring accuracy, range, speed, and functions – the only difference is the control panel: SN‑1E uses physical buttons, while SN‑1S uses a touchscreen. Both must be connected to a PC with dedicated test software for test setup, data acquisition, and report generation.

2. Functional Differences

Test coverage:

• SN‑1E / SN‑1SE: Most comprehensive – tensile, bending, puncture, seal, peel, heat seal, tear, shear, elastic modulus, etc.
• SN‑2SE / SN‑2CE: Tensile, peel, heat seal, tear, puncture.
• SN‑2E / SN‑3E: Tensile, peel, heat seal, tear.
• SN‑DE: Tensile, compression, bending, peel, spring tests, etc.

Operation modes:

• SN‑1E / SN‑1SE: Require PC connection; professional software for operation and data management. SN‑1E uses physical buttons for parameter input, SN‑1SE uses touchscreen input – software functions are identical.
• SN‑2E / SN‑2SE / SN‑2CE / SN‑3E: Built-in touchscreen or LCD for standalone operation – no external PC needed; integrated thermal printer for instant output.
• SN‑DE: PC digital control with curve display and data processing via computer.

Standard configurations:

• SN‑1E / SN‑1SE: Includes tensile grips + puncture fixture + professional software.
• SN‑2SE / SN‑2CE: Includes tensile grips + puncture fixture.
• SN‑2E / SN‑3E / SN‑DE: Includes tensile grips only.

3. Standards Compliance

All seven models comply with the following domestic and international standards:

• Chinese standards: GB 8808, GB 13022, GB/T 1040, GB/T 7753, GB/T 7754, GB/T 453, GB/T 17200, GB/T 16578.1, QB/T 1130, GB/T 2790, GB/T 2791, GB/T 2792, GB/T 10004, GB/T 17590, JJG 139, GB/T 6344, GB 10808
• Pharmaceutical packaging standards: YBB 00112003, YBB 00102003, YBB 00132002, YBB 00202004
• ASTM standards: ASTM D828, ASTM E4, ASTM D882, ASTM D1938, ASTM D3330, ASTM F88, ASTM F904
• Others: JIS P8113, QB/T 2358

Notably, ASTM D882 is the standard test method for tensile properties of thin plastic films (thickness <1mm), and GB/T 1040.3 is the Chinese national standard for the same – Sunuo's full series meets these core requirements.

Selection Guide

1. By Application Scenario

▶ High-precision, full-featured / R&D and quality inspection → Recommend SN‑1E or SN‑1SE

Both offer Class 0.5 sensor accuracy, 0.001N force resolution, 1250% elongation, and cover all test types (tensile, bending, puncture, peel, heat seal, tear, shear, elastic modulus). The only difference is the operation preference:

• Choose SN‑1E if you prefer physical button feedback.
• Choose SN‑1SE if you prefer a touchscreen interface.

Both require a PC and printer – ideal for universities, inspection agencies, and comprehensive laboratories.

▶ Standalone operation / no PC required → Recommend SN‑2SE or SN‑2CE

If you don't want to occupy a computer, these are ideal – they have built-in screens and thermal printers, capable of performing tensile, peel, heat seal, tear, and puncture tests independently. SN‑2CE offers higher displacement accuracy (0.001mm), suitable for applications demanding precise deformation measurement. Perfect for daily quality control in food and pharmaceutical packaging plants.

 ▶ Economical & compact / limited space → Recommend SN‑3E

Smallest footprint (490×300×1140mm), 300N range, touchscreen standalone operation, covering basic tensile, peel, heat seal, and tear tests – excellent value. Suitable for small packaging enterprises or quick on-line testing next to production lines.

▶ Budget-conscious / basic functions → Recommend SN‑2E

300N economical model with touchscreen + thermal printing, supports tensile, peel, heat seal, tear – no puncture function. Choose this if puncture testing is not required and affordability is key.

▶ Heavy-load / multi-material versatility → Recommend SN‑DE

Dual-column portal structure, up to 50KN, not only for plastic films but also for metals, rubber, textiles, electronics, etc. Effective specimen width 400mm – ideal for comprehensive enterprises and third-party testing laboratories.

2. By Key Parameter Requirements

 3. By Industry Recommendation

• Plastic film manufacturers: Recommend SN‑1SE (touchscreen convenience) or SN‑2CE (standalone operation) – fully meeting film tensile, tear, puncture, etc.
• Food packaging companies: Recommend SN‑2SE – covers heat seal strength, peel strength, and other key tests without needing a PC.
• Pharmaceutical packaging companies: Recommend SN‑1E or SN‑1SE – meets all YBB pharmacopoeia standards with high accuracy.
• Quality inspection / testing agencies: Recommend SN‑1E (keypad) or SN‑1SE (touchscreen) – full functionality, high accuracy, and fully traceable data.
• Universities / research institutes: Recommend SN‑1E or SN‑1SE – most comprehensive functions and highest accuracy, ideal for teaching and research.
• Multi-material enterprises: Recommend SN‑DE – one machine for multiple uses, covering metals, plastics, rubber, and more.

Summary

Sunuo's full series of tensile testing machines, centered around plastic film tensile testing machines, builds a complete product range from 300N to 50KN, from single-column to dual-column, and from standalone operation to PC control:

• SN‑1E / SN‑1SE: 500N high-precision flagship, full functions, require PC, available in keypad or touchscreen variants.
• SN‑2E / SN‑2SE / SN‑2CE: 300N standard series, standalone touchscreen operation, meeting all daily quality control needs – SN‑2CE offers higher displacement accuracy.
• SN‑3E: Compact and economical – ideal for users with limited space.
