Is plastic or stainless steel better for stainless steel thermos cup lids? (Part 2)

Hello everyone, "Dong Dong Talk Cup" is here. Most of the stainless steel thermos cup lids sold on the market are made of plastic, and some are made of stainless steel. What is the difference between these two materials? http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlIn the last article, Uncle Dong brought you the advantages and disadvantages of plastic cup lids. In this article, Uncle Dong will continue to share with you the characteristics of stainless steel cup lids.

Environmental issues: Currently, the plastic materials used for stainless steel thermos cup lids are mostly made of PP, Tritan and other materials. These materials are not degradable, so if recycling is not managed scientifically, it will have a long-term impact on the environment. http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlOf course, some cup lids are made of plant-degradable materials such as PLA, but considering that the material may degrade rapidly after long-term contact with water, more manufacturers will use this type of material mixed with PP material, so the final mixed plastic cup lid is still not easy to degrade.

What are the advantages and disadvantages of stainless steel cup lids?

Advantages:

High temperature resistance: Stainless steel can withstand higher temperatures and will not deform due to high temperatures, http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlmaking it more suitable for hot drinks.

Strong durability: Stainless steel is much more durable than plastic, is not easily damaged, and has a longer service life.

Environmental protection and health: Stainless steel is a recyclable material, which is more environmentally friendly. At the same time, stainless steel does not release harmful substances and is safer to use. http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlThe editor would like to emphasize that the stainless steel that does not release harmful substances here refers to qualified food-grade stainless steel, mainly 304 stainless steel and 316 stainless steel.

Disadvantages:

Weight: Stainless steel cup lids are heavier than plastic cup lids, which may be a little inconvenient to carry.

Insulation is worse than plastic: Since stainless steel is more complicated to shape and has a higher molding cost, stainless steel thermos cups that usually use stainless steel as cup lids are usually simpler in design, especially in structure. If the cup lid is made of only stainless steel and silicone, the insulation performance is indeed worse than that of a plastic cup lid. http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlFor this reason, when designing such products, manufacturers usually design the stainless steel cup lid into a double-layer structure. If production conditions allow, the double-layer stainless steel cup lid will be vacuumed to achieve a better insulation effect for temperature transfer.

Cost: The cost of stainless steel cup lids is higher than that of plastic cup lids, which mainly depends on the difficulty of material processing and the material cost.

The choice of plastic or stainless steel cup lids ultimately depends on market needs and product functionality. If you focus on lightness and cost-effectiveness, http://www.zhanyict.com/en/ProductsDetail-VB-10491.htmlplastic cup lids may be a better choice; if you focus on durability, environmental protection factors and brand positioning, stainless steel cup lids will be a more ideal choice.
