Rubber thread’s flexibility makes it one of the most sought-after materials in the world. Its versatility for various purposes keeps rubber thread in high demand across multiple industries, including food packaging. The elastic properties and adaptability of rubber thread to meet global requirements make it an ideal material for manufacturing safe and reliable food packaging. Features such as its ability to create a tight seal to secure food items and prevent spoilage further demonstrate why this material is chosen by many.

But what requirements must rubber thread manufacturers fulfill for their products to be safely used in direct contact with food? What certifications and safety standards are necessary?
Safety standards rubber thread producer has to fulfilled to ensure it is safe for food packaging
Come in neutral or natural shades : When producing rubber thread explicitly for food packaging, it is essential to use coloring in neutral shades coated with talc. These shades must be certified safe for direct contact with food or accidental consumption by the customer. Neutral and natural shades are preferred because they contain fewer artificial colorings. Typically more muted, neutral colors don't require the addition of synthetic chemicals for enhancement. In contrast, artificial coloring is prevalent in bright and vibrant shades to intensify their appearance. Omnimax by PT. Cilatexindo Graha Alam, as one of the leading food-grade rubber thread manufacturer implemented this, as they only produce neutral color rubber thread that come in white and black shades.
Temperature resistance : When using rubber thread for packaging food items, it is crucial to ensure that it meets safety standards. The thread must undergo tests to verify its resistance to high temperatures, as it will be exposed to different weather conditions during transportation, stored in various locations, and transported in different vehicles. Additionally, the thread should not melt easily when exposed to high temperatures and should retain its flexibility even in low temperatures to ensure it can form a tight and secure seal around food items, keeping them fresh.
Technical specifications : When producing rubber threads for specific applications, it is crucial to adhere to specific specifications. For example, if the rubber thread is intended for food packaging, it should have a count range of 20 to 40 and a tensile strength of at least 20 MPa (Mega Pascal). These specifications ensure the rubber thread can withstand the rigorous food packaging process, safeguarding the integrity of food items. Additionally, it should exhibit an elongation break of over 700% and a Schwartz value of 100 g/square mm to guarantee durability and meet the suitability standards for food packaging.
In conclusion, rubber thread is a versatile material with various applications. Its flexibility allows customization to meet specific manufacturing needs. Due to its exceptional elasticity and durability, rubber thread is suitable for food packaging, aiding in sealing and maintaining food freshness for extended periods. It's crucial to source rubber thread for food packaging exclusively from a trusted manufacturer like Omnimax by PT. Cilatexindo Graha Alam, which consistently adheres to strict guidelines and obtains necessary certifications. Serving as a carrier and coating for food, rubber thread ensures the safe consumption of our families.
