Why can’t pure coffee grounds be used to produce water cups?

Hello everyone, "Dong Dong Talk Cup" is here. With the increasing awareness of environmental protection among the public, various types of renewable resources are being used more and more in different production fields. http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlAmong them, the water cup industry is also increasingly using various types of renewable materials, such as PLA, coffee grounds, etc. However, when using coffee grounds in water cup production, you need to pay attention to multiple issues to ensure the safety, durability, functionality and rationality of the product. Today, the editor will share with you why you can't use pure coffee grounds to produce water cups?

1. Insufficient mechanical strength

Pure coffee grounds are a loose material that lacks sufficient mechanical strength and toughness. http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlIf you use pure coffee grounds directly to make a water cup, the product will be very fragile and unable to withstand the pressure and impact of daily use.

2.Poor waterproofness

Coffee grounds themselves are absorbent. If used directly to make water cups, http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlthe product will easily seep water and fail to meet the basic functional requirements of water cups.

3. High processing difficulty

Pure coffee grounds cannot be formed through conventional injection molding or hot pressing processes. http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlThey lack plasticity and are difficult to make into products of complex shapes.

4. Easy to deteriorate

Pure coffee grounds are an organic material that is susceptible to moisture, http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlmold or decomposition, affecting the product's service life and hygienic performance.

Why use PP combined with coffee grounds or ABS combined with coffee grounds for production?

1. What are the advantages of combining PP (polypropylene) with coffee grounds?

Excellent mechanical properties: PP is a common plastic material with good mechanical strength and toughness, which can make up for the lack of strength of coffee grounds.

Good heat resistance: http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlPP has high heat resistance and is suitable for making products such as water cups that need to withstand a certain temperature.

Food safety: PP is a food grade material, non-toxic and harmless, suitable for making food containers.

Good processing performance: http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlPP is easy to process and can be evenly mixed with coffee grounds to make products with excellent appearance and performance.

2. What are the advantages of combining ABS (acrylonitrile butadiene styrene copolymer) with coffee grounds?

High strength and toughness: http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlABS has excellent mechanical properties and can significantly improve the strength and durability of the coffee grounds water cup.

High surface gloss: Products made of ABS have a smooth surface and good texture, which can improve the appearance quality of the water cup.

Chemical resistance: http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlABS has good tolerance to water and general chemicals and is suitable for making water cups.

Processing flexibility: ABS is easy to process and can be combined with coffee grounds to form products of various shapes and sizes.

3. Environmental protection and sustainability

By combining coffee grounds with PP or ABS, not only can the use of plastic be reduced, http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlbut also new value can be given to waste coffee grounds, which is in line with the concept of environmental protection and sustainable development.

In summary, during the production process of water cups made of coffee grounds, attention should be paid to material ratio, processing temperature, mildew prevention, product strength, food safety and appearance texture. http://www.zhanyict.com/en/ProductsDetail-VB-10497.htmlPure coffee grounds are not suitable for direct use in the production of water cups due to insufficient mechanical strength, poor waterproofness and high processing difficulty. By combining coffee grounds with PP or ABS, the advantages of both can be fully utilized to produce water cups that are both environmentally friendly, functional and aesthetically pleasing.
