A fragile or poorly executed weld can have serious consequences: product leakage, loss of tightness, contamination, or even the recall of entire batches. To avoid these risks, manufacturers need accurate measuring tools capable of verifying the quality of seals. The <strong>Peeltest<\/strong>, also known as a peel test bench, is an essential solution as it allows the mechanical strength of welds to be checked and ensures that packaging complies with current standards. This property, known as <strong>peelability<\/strong>, is the force needed to open a sealed package without tearing it: it directly affects both product safety and ease of opening for the end user.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"what-is-a-peel-tester\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-df09a22a0e64ef9996810d5521f6c960\">What is a Peel tester?<\/h2>\n\n\n\n<h3 id=\"definition-of-peel-tester\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-c7d608f0edcc3d9441047c1918b675d7\">Definition of Peel tester<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-e6db6a2f4de5e4b3976240746214bc13 wp-block-paragraph\">The Peeltest is a measuring instrument that evaluates the force required to separate two bonded surfaces. It is mainly used to test the strength of flexible packaging such as plastic films, bags, blister packs, and medical pouches. The result, expressed in newtons per unit width, makes it possible to quantify the peelability of the weld precisely and compare it against the thresholds set by specifications or the applicable standard.<\/p>\n\n\n\n<h3 id=\"operating-principle\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-c9ce1ffa4d2e15deae371bc694bb1ed0\">Operating principle<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-589e59f482adfa13197d0fcdc5fcabbd wp-block-paragraph\">The sample to be tested is cut and then inserted into the Peeltest jaws. The machine applies controlled traction to both welded parts and records the force applied until breakage occurs. This makes it possible to determine whether the weld is uniform and sufficiently strong to meet safety requirements.<\/p>\n\n\n\n<h3 id=\"difference-from-other-test-equipment\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-7a27bad10bec09204239d90e5ec39b50\">Difference from other test equipment<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-067e154b110c103ba5a505be6c5b148f wp-block-paragraph\">Unlike a tensile testing machine, which measures the overall strength of a material, the Peeltest focuses exclusively on the <strong>quality of welds<\/strong>. It is a tool specialized in evaluating sealants, not raw materials.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"why-use-a-peel-tester\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-9e9c87b1616bfbef37522d27e9fa9854\">Why use a peel tester?<\/h2>\n\n\n\n<h3 id=\"ensuring-the-quality-of-welds\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-c6afe2b638008c9cb5cd9d86ef2cd480\">Ensuring the quality of welds<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-0df026aaa6940744008cb9c8b211ab87 wp-block-paragraph\">The Peeltest ensures precise control of the adhesion and regularity of welds. It highlights invisible defects, such as insufficient pressure, incorrect temperature settings, or the presence of impurities in the sealing area.<\/p>\n\n\n\n<h3 id=\"compliance-with-standards-and-regulations\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-c006f60db5d8fdeb8e02afd24f0f52e9\">Compliance with standards and regulations<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-5cd30ac7df4f6622a9f12c5321a920a8 wp-block-paragraph\">Many industries require standardized testing to validate packaging compliance. In the medical and pharmaceutical fields, for example, ISO 11607 defines the criteria for validating sterile packaging. The food and cosmetics industries are also subject to strict controls to ensure health safety and consumer satisfaction.<\/p>\n\n\n\n<h3 id=\"risk-and-cost-reduction\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-cd3ce3c4959afe1a4e0c6cd523129d58\">Risk and cost reduction<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-e6179ce4adf777f2aaa262bad89ef5a8 wp-block-paragraph\">A packaging defect can have major financial and reputational consequences. Using the Peeltest helps limit product losses, avoid costly recalls, and protect the brand against litigation related to non-compliance.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"the-main-applications-of-peel-testing-equipment\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-c971c7ecb82414534b88a0d0422fbd2d\">The main applications of peel testing equipment<\/h2>\n\n\n\n<h3 id=\"agri-food-sector\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-3f71b9758caf3afa289fdedf740a1d47\">Agri-food sector<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-dbe15b7342585f2b9c9372faf86c28fb wp-block-paragraph\">Packaging bags, trays, and films must be completely airtight to preserve food quality. The Peeltest validates the strength of welds and prevents any risk of leakage or contamination.<\/p>\n\n\n\n<h3 id=\"pharmaceutical-and-medical-industry\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-6a58478a81cde554e8af7628511f97d0\">Pharmaceutical and medical industry<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-260fd8a7cf4d20ebc083d6a0edeff187 wp-block-paragraph\">In this sector, safety is vital. The Peeltest is used to check the strength of welds on infusion bags, tablet blister packs, or sterile pouches. These tests ensure that the packaging remains sterile and tamper-proof until use.<\/p>\n\n\n\n<h3 id=\"cosmetics-and-hygiene\" class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-f53cfd2fc727496b2cdc3c415be6fd78\">Cosmetics and hygiene<\/h3>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-345347e885fbe4e05ff34fd668f80a09 wp-block-paragraph\">Single-dose packaging, samples, and sealed sachets must be sturdy but easy for consumers to open.
