YYP-L1 Electronic universal testing machine(Plastic film tensile testing machine)In fields such as industrial manufacturing, packaging material production, and quality inspection and testing, plastic film tensile testing instruments are indispensable core detection equipment. Their necessity lies in multiple key aspects including quality control, compliance, cost control, and product iteration. The details are as follows:
1.Guarantee product quality and performance stability:
The tensile properties of plastic films (such as tensile strength, elongation at break, elastic modulus, etc.) are the core indicators for measuring their durability, tear resistance, and load-bearing capacity.
1)For packaging films (food packaging, industrial packaging), sufficient tensile strength can prevent damage and leakage during transportation due to compression and pulling; appropriate elongation at break can adapt to packaging forming processes (such as the contraction effect of heat shrinkable films).
2)For industrial films (agricultural mulch films, electronic films), tensile properties directly affect their wind resistance, aging resistance, and puncture resistance.
The tensile tester quantifies these indicators precisely, ensuring that each batch of films meets the design standards and avoiding product scrapping or customer complaints due to non-compliant performance.
2.Meet industry standards and compliance requirements
There are clear testing standards for plastic films both domestically and internationally, such as:
National Standard GB/T 1040.3-2006 “Plastics – Determination of Tensile Properties – Part 3: Test Conditions for Films and Sheets”
International Standard ISO 527-3:1995 corresponding tensile test specifications for films
Whether for domestic sales of film products or export orders, it is necessary to provide a compliant report tested by the tensile tester to pass the quality inspection department’s acceptance or meet the customer’s entry requirements. Without this equipment, the product will not obtain compliance qualifications and lose market access qualifications.
3.Optimize production processes and reduce costs
The test data from the tensile tester can guide the adjustment of production processes in reverse:
1)When the test detects low tensile strength, targeted optimization can be made to the raw material formula (such as adjusting resin grades, adding toughening agents) or production parameters (such as adjusting blow-molding temperature, traction speed).
2)By comparing the tensile performance data of different batches and different raw materials, the most cost-effective raw material solution can be selected, ensuring performance while reducing raw material costs.
At the same time, detecting unqualified batches in advance can prevent unqualified films from flowing into downstream processes (such as printing, bag-making), reducing additional costs such as rework and waste disposal.
4.Support product research and development and innovation
In the research and development process of new plastic films (such as biodegradable films, high-strength composite films), the tensile tester is a key tool for evaluating the feasibility of formulas and processes.
R&D personnel can test the tensile performance curves of different formula films, analyze the mechanical properties of the materials, and then optimize the formula design to develop new products that meet specific scene requirements (such as highly elastic food packaging films, highly tensile industrial wrapping films).
5.Respond to customer acceptance and trade disputes
In international trade or bulk order cooperation, customers usually require a third-party or in-house tensile performance test report as the acceptance basis.
Having an independent tensile tester, being able to complete the test independently and issue the data, not only shortens the acceptance cycle but also provides objective and accurate test data as a basis for rights protection when there are trade disputes, avoiding the passive situation of evidence presentation due to reliance on external testing institutions.
Summary
For enterprises engaged in the production, processing and quality inspection of plastic films, especially those involved in export trade, tensile testing equipment is not an optional item but a necessary one – it is the “gatekeeper” of quality, the “passport” for compliance, the “controller” of costs, and the “supporting point” for product competitiveness.
