style=\"font-weight: 400;\">&#8220;Food-grade plastic&#8221; does not refer to a specific type of plastic; rather, it denotes plastic materials that meet safety requirements for food contact and are suitable for direct or indirect contact with food.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Food_Safe_Plastic\"><\/span><span style=\"font-weight: 400;\">What is Food Safe Plastic?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Food-safe plastics are plastics that, when used for their intended purpose, avoid safety hazards. This is because even materials classified as food-grade can pose safety risks if used improperly or beyond their specified limits.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Whats_the_Difference_Between_Food-Grade_and_Food-Safe\"><\/span><span style=\"font-weight: 400;\">What\u2019s the Difference Between Food-Grade and Food-Safe?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">&#8220;Food-grade&#8221; plastic is not necessarily &#8220;food-safe&#8221; plastic. You can think of it this way: food-grade plastic falls under the category of food-safe plastic. This is because &#8220;food-grade&#8221; refers to the plastic material itself meeting requirements for food contact, whereas &#8220;food-safe&#8221; implies that the plastic poses no risk to the food in a specific application.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_standards_must_food-grade_plastics_meet\"><\/span><span style=\"font-weight: 400;\">What standards must food-grade plastics meet?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Food-grade plastics must comply with relevant FDA regulations. The FDA (U.S. Food and Drug Administration) has established specific rules regarding plastic products that come into contact with food.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Specifically, FDA 21 CFR Part 177 outlines which polymers are permitted for food contact and specifies the additives allowed for use. Additives are chemical substances incorporated during the production and preparation of polymers to facilitate molding or to modify physical and chemical properties\u2014such as stabilizers, antioxidants, and lubricants<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_is_it_necessary_to_control_additives\"><\/span><span style=\"font-weight: 400;\">Why is it necessary to control additives?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Not all additives are permitted for use in food-contact materials, as the issue of chemical migration is involved. Certain additives may migrate into food during use, potentially increasing food safety risks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, the FDA regulates the use of additives and mandates that the amount migrating into food remains below established regulatory limits, thereby safeguarding consumer safety.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_are_the_different_types_and_applications_of_food-grade_plastics\"><\/span><span style=\"font-weight: 400;\">What are the different types and applications of food-grade plastics?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"UHMW-PE\"><\/span><span style=\"font-weight: 400;\">UHMW-PE<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/hansaplas.com\/ja\/uhmwpe-sheet\/\"><span style=\"font-weight: 400;\">UHMW-PE<\/span><\/a><span style=\"font-weight: 400;\"> stands for Ultra-High Molecular Weight Polyethylene and is most commonly used in food processing equipment. Its key characteristics include wear resistance, impact resistance, and self-lubricating properties; with a friction coefficient of 0.05\u20130.15, it requires no additional lubricant when operating as a gear or guide rail. It is often used as a substitute for metal to reduce equipment wear and noise.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">UHMW-PE has a long-term service temperature range of -200\u00b0C to 80\u00b0C, making it suitable for low-temperature, high-impact operating conditions. Its short-term service temperature is 90\u2013100\u00b0C; it is not suitable for use at high temperatures.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Thanks to its excellent mechanical properties\u2014particularly wear resistance and low friction\u2014as well as its compliance with FDA regulations, UHMW-PE is widely used in the food processing industry for applications such as conveyor guide rails, chain guides, and beverage transport piping.<img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-23882 aligncenter\" src=\"http:\/\/hansaplas.com\/wp-content\/uploads\/2026\/07\/UHMW-PE-conveyor-guide-rail.jpg\" alt=\"UHMW-PE conveyor guide rail\" width=\"700\" height=\"450\" srcset=\"https:\/\/hansaplas.com\/wp-content\/uploads\/2026\/07\/UHMW-PE-conveyor-guide-rail.jpg 700w, https:\/\/hansaplas.com\/wp-content\/uploads\/2026\/07\/UHMW-PE-conveyor-guide-rail-18x12.jpg 18w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"HDPE\"><\/span><span style=\"font-weight: 400;\">HDPE<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/hansaplas.com\/ja\/hdpe-sheet\/\"><span style=\"font-weight: 400;\">HDPE<\/span><\/a><span style=\"font-weight: 400;\"> stands for High-Density Polyethylene. Like UHMW-PE, it is a type of polyethylene (PE), but it differs in molecular weight, which results in different performance characteristics. HDPE offers greater rigidity than UHMW-PE, is easier to process, and is more cost-effective. However, its long-term operating temperature range is limited to -50\u00b0C to 80\u00b0C; it is suitable only for standard temperature environments, as its heat resistance is moderate.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">HDPE is actually most widely used in household settings rather than industrial applications. For instance, most cutting boards\u2014aside from wooden ones\u2014are made of HDPE. It does not harbor bacteria, does not easily dull knives, and complies with FDA regulations, making it safe for contact with food and the human body.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Beyond cutting boards, HDPE is used for long-term food storage, such as in milk jugs, squeeze bottles for chocolate or butter spreads, and shopping bags.

It also features low friction\u2014with a coefficient of just 0.04\u2014and low surface adhesion, resulting in non-stick characteristics that make cleaning easy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Food-grade PTFE is suitable for use in food processing equipment, particularly for seals, conveyor system components, and sliding parts.

Soft PVC contains plasticizers, and its suitability for food contact depends on the specific formulation and the type of plasticizer used.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, before use, the material should undergo FDA testing to determine whether it complies with relevant FDA regulations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">PVC offers excellent chemical resistance and ease of processing.

This is because PE is only heat-resistant up to 80\u00b0C; prolonged exposure to higher temperatures causes the material to soften and degrade in performance, leading to a loss of dimensional stability and creating potential risks.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Heavy_Wear_Applications\"><\/span><span style=\"font-weight: 400;\">Heavy Wear Applications <\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For applications involving long-term, high-wear conditions, the use of PP or PVC plastics is not recommended. Their low wear resistance leads to more frequent replacements, indirectly increasing your project costs. UHMW-PE is the preferred choice, as HDPE does not match its wear resistance.

PTFE is the most cost-effective food-grade plastic; alternatively, if the application involves high-end equipment requiring material rigidity, you could opt for PEEK.
