class=\"wp-block-paragraph\">For food brands and buyers, a common pitfall when choosing packaging is focusing on the bag type while neglecting the material structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even with stand-up pouches or three-side seal bags, different material combinations can lead to completely different packaging performance. For example, some packaging effectively extends product shelf life, while others are better suited for showcasing the product&#8217;s appearance, and still others are better suited for frozen transport or high-fat foods. If the material structure is chosen inappropriately, even with excellent printing, problems such as moisture absorption, air leakage, oxidation, or packaging damage may occur.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.zkprintpack.com\/fr\/produit\/custom-sauce-packaging-bags-wholesale\/\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1.webp\" alt=\"Fabricant de sachets d&#039;emballage alimentaire sur mesure - 1\" class=\"wp-image-2629\" srcset=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1.webp 800w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-150x150.webp 150w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-768x768.webp 768w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-12x12.webp 12w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-600x600.webp 600w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-300x300.webp 300w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2026\/02\/custom-sauce-packaging-bag-manufacturer-1-100x100.webp 100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, when purchasing <strong><a href=\"https:\/\/www.zkprintpack.com\/fr\/custom-stand-up-pouch\/\" target=\"_blank\" rel=\"noreferrer noopener\">sacs d'emballage alimentaires personnalis\u00e9s<\/a><\/strong>, instead of simply comparing prices, it&#8217;s better to first understand the functions of various packaging materials and how they can be combined to meet the packaging needs of different foods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article will guide you through understanding the seven most common materials used in flexible food packaging from the perspective of a packaging manufacturer, and introduce their characteristics in practical applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Do_Food_Packaging_Generally_Use_Multi-Layer_Composite_Structures\"><\/span>Why Do Food Packaging Generally Use Multi-Layer Composite Structures?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modern food packaging rarely uses a single material because each material has its own advantages and limitations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, one material may have excellent printability but cannot be heat-sealed; another material may have excellent barrier properties but lack mechanical strength.

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">From a packaging manufacturer&#8217;s perspective, no single material structure is suitable for all products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A truly reasonable solution requires a comprehensive assessment of the following aspects:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Product_Type\"><\/span>Type de produit<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Different foods have different requirements for oxygen barrier, moisture protection, oil resistance, and puncture resistance; therefore, material combinations will also differ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, coffee products typically prioritize aroma retention, while pet food places greater emphasis on barrier properties and packaging strength.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Shelf_Life_Requirements\"><\/span>Shelf Life Requirements<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If a product requires a longer shelf life, a composite structure with higher barrier properties is usually needed, rather than simply increasing packaging thickness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Transportation_Method\"><\/span>Transportation Method<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Exported products may undergo long-term sea freight, warehousing, and temperature and humidity fluctuations; therefore, packaging not only needs to protect the product but also needs to possess stable physical properties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Automated_Packaging_Equipment\"><\/span>Automated Packaging Equipment<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Different filling equipment has different requirements for the coefficient of friction, stiffness, and heat-sealing performance of packaging materials; therefore, the packaging structure should be matched to the production process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Professional packaging manufacturers typically recommend more suitable <strong><a href=\"https:\/\/www.zkprintpack.com\/fr\/produit\/custom-stand-up-pouches-for-powder\/\" target=\"_blank\" rel=\"noreferrer noopener\">sachet d'emballage alimentaire personnalis\u00e9<\/a><\/strong> structures based on the product information provided by clients, rather than adopting a uniform solution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span
