What are the advantages of double-layer paper cups compared to single-layer paper cups besides insulation?

What are the advantages of double-layer paper cups compared to single-layer paper cups besides insulation?

The double-layer paper cup adopts a design of "double-layer cardboard+middle air layer", and its structural strength is much higher than that of single-layer paper cups. On the one hand, it has stronger resistance to deformation - when filling liquids (especially hot or large capacity drinks), the cup body is less likely to "collapse" due to temperature changes (thermal expansion and contraction) or handle pressure. For example, when filling 500ml or more hot coffee, single-layer cups may sink inward due to weight and high temperature, while double-layer cups can maintain an upright shape and reduce the risk of tipping over; On the other hand, the leakage prevention performance is better. If the inner coating is slightly damaged due to production defects or friction, the outer cardboard can serve as a "secondary barrier" to delay or even prevent liquid leakage and prevent hands from getting wet. This is particularly practical in hot beverage delivery, as it can handle minor leakage issues caused by bumps.

Can paper bowls be heated in a microwave?

Can paper bowls be heated in a microwave?

Avoid using ordinary plastic: Hot food can cause plastic containers to deform, and ordinary plastic can release toxic substances, contaminate food, and harm human health. Avoid using metal utensils: Because iron, aluminum, stainless steel, enamel and other utensils placed in the oven will generate electric sparks and reflect microwaves when the microwave is heated, which not only damages the oven body but also cannot heat food.

What is the difference between single-layer paper cups and double-layer paper cups? How should I choose?

What is the difference between single-layer paper cups and double-layer paper cups? How should I choose?

Single layer paper cup is one of the disposable paper cups, also known as single-sided coated paper. That is to say, the layer inside the paper cup has a smooth PE forest film single-layer cup, which is generally used to hold drinking water and facilitate people's drinking. The single room material is made of food grade pasture paper and food grade PE film.Double layered paper cups, as the name suggests, refer to paper cups with 2 layers, and the quality of double-layer paper cups is better than single-layer paper cups. The usage time of double-layer paper cups is also longer than that of single-layer paper cups. It can also be used to hold hot beverages, such as hot coffee.

What are the core product advantages of hollow paper cups?

What are the core product advantages of hollow paper cups?

The air in the hollow layer is a poor conductor of heat and can effectively block heat transfer: when filled with 80°C hot water, the temperature of the outer cup wall can be controlled below 40°C (the temperature of the outer cup wall of a traditional single-layer paper cup can reach over 60°C, making it easy to burn your hands). It has a wide range of applicable temperatures: it can hold liquids from -10°C (cold drinks) to 95°C (hot water), and the outer cup wall is not prone to condensation at low temperatures (to avoid slippery hands).

What are the printing methods for paper cups?

What are the printing methods for paper cups?

Offset printing utilizes the principle of oil and water repulsion. Paper cups are selected for publication in the graphic and text department, and movies promote their hydrophilicity and resistance to oil and water. Blank areas are hydrophilic and resistant to oil, and the graphic and text are transferred onto the substrate through a rubber blanket cylinder. The advantage of offset paper cups is that the pattern colors are full, vivid, and have high clarity. Both gradient and fine lines can be well displayed, making the appearance of the paper cup more beautiful and attracting customers' attention. However, offset printing is not suitable for printing edible paper cups because offset printing ink is not very environmentally friendly.

What is the difference between a cold cup and a hot cup?

What is the difference between a cold cup and a hot cup?

Cold cups, also known as disposable paper cups, have a layer of edible wax on their surface. Cold drinks can cause water to accumulate on the surface of the paper cup, leading to its hardening. Applying wax can make it waterproof. At 0-5 ℃, this wax is particularly stable and safe. But if the temperature of the beverage exceeds 62 ℃, the wax will solidify and the paper cup will absorb water and deform. Unlike cold cups, hot cups are coated with a special layer of polyethylene film, which not only has good heat resistance, but also is non-toxic and harmful when soaked in low-temperature beverages.

How are paper cups, paper bowls, and paper buckets divided

How are paper cups, paper bowls, and paper buckets divided

A. Measurement units: commonly used ounces (OZ) and milliliters (cc, ml) to measure the size of capacity;B. According to the size of the caliber and domestic customs, they are divided into paper cups, paper bowls, and paper buckets. Paper cup: In China, we refer to cups that are 3-18 ounces (OZ) in size as paper cups;Paper Bowl: Paper cups weighing 20-60 ounces are called paper bowls. (The diameter of the bowl is larger than that of the paper cup. If the bottom diameter exceeds 70mm, a paper bowl machine is needed to produce paper bowls.);
