The first step in selecting high barrier packaging film is understanding the specific protection requirements of the product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Par exemple :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potato chips, biscuits, and other puffed snacks require strong moisture barrier performance to maintain crispness.<\/li>\n\n\n\n<li>Coffee, tea, and nuts with higher oil content require better oxygen barrier properties to prevent oxidation and flavor loss.<\/li>\n\n\n\n<li>Liquid food products require both strong barrier performance and reliable heat sealing performance.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">By identifying the product characteristics and target shelf life, brands can select a more suitable <strong><a href=\"https:\/\/www.topchinapack.com\/fr\/custom-solution\/\" target=\"_blank\" data-type=\"page\" data-id=\"358\" rel=\"noreferrer noopener\">custom packaging solution<\/a><\/strong> instead of choosing packaging materials based only on cost or specifications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Choose_the_Right_Composite_Film_Structure\"><\/span>Choose the Right Composite Film Structure<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">High barrier roll stock film usually uses multi-layer laminated structures. Different material combinations provide different levels of protection and are suitable for different food applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"PETVMPETPE_Structure\"><\/span>PET\/VMPET\/PE Structure<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PET\/VMPET\/PE<\/strong> is a commonly used high barrier structure that provides good oxygen barrier, moisture barrier, and light protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Il convient pour :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Potato chips<\/li>\n\n\n\n<li>Bonbons<\/li>\n\n\n\n<li>Biscuits<\/li>\n\n\n\n<li>Other dry snacks<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This structure offers a good balance between packaging performance and cost, making it a popular choice for many food brands.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

moisture protection<\/li>\n\n\n\n<li>Excellent light blocking performance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This structure is commonly used for products with higher shelf life

class=\"wp-block-paragraph\">For products that require long-term freshness protection, this type of high barrier food packaging film can provide more reliable protection.<\/p>\n\n\n\n<h3

Performance Indicators<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When choosing high barrier roll stock film, several technical indicators should be considered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Important factors include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Oxygen_Transmission_Rate_OTR\"><\/span>Taux de transmission de l'oxyg\u00e8ne (OTR)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OTR measures how easily oxygen passes through the packaging material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A lower OTR value means better oxygen barrier performance, which is especially important for products sensitive to oxidation, such as coffee, nuts, and oily foods.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Water_Vapor_Transmission_Rate_WVTR\"><\/span>Taux de transmission de la vapeur d'eau (WVTR)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">WVTR indicates the moisture barrier ability of the packaging film.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A lower WVTR helps prevent moisture absorption and protects products such as snacks, powders, and dry foods from quality deterioration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Heat_Seal_Strength\"><\/span>Heat Seal Strength<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Heat sealing performance directly affects packaging integrity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Higher seal strength provides stronger sealing reliability, reducing the risk of leakage and external contamination while helping extend food shelf life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When selecting food packaging roll film, these performance indicators should be evaluated together based on the actual product requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
