II. Analysis of Complaints in Different Beverage Scenarios
2.1 Complaints in Hot Beverage Scenarios
Hot beverage scenarios are the most frequent usage scenarios for paper cups and also the area with the most concentrated complaints. In hot beverage scenarios, the influence of temperature on paper cup performance is the main factor leading to complaints.
Complaints in coffee scenarios mainly focus on the heat resistance and structural stability of custom-printed paper cups. According to consumer feedback, when using single-layer paper cups to hold hot coffee at 90℃-95℃, the outer surface temperature of the cup can reach 65℃-70℃, easily causing burns to the hands. More seriously, some lower-quality paper cups will experience bottom detachment or cup body cracking within 15 minutes of holding hot coffee. The Canadian Tim Hortons coffee chain once faced large-scale complaints due to paper cup quality problems. Consumers reported frequent and serious problems, such as complete bottom detachment and disintegration of the cup body seams during use, leading to hot coffee spills and burn risks.
Complaints in milk tea scenarios show more diverse characteristics. Firstly, there are temperature-related complaints, particularly the common problem of hot drink cups softening after holding 85℃ milk tea for 15 minutes in winter, resulting in a customer complaint rate as high as 12%. Secondly, there are inconsistencies in packaging specifications; some consumers have complained that the same store uses paper cups wholesale for takeout but injection-molded cups for dine-in, causing a difference in experience. In addition, ingredients such as tapioca pearls and coconut jelly in milk tea may also lead to cup softening or leakage problems.
Complaints in hot beverage scenarios mainly involve the material safety of paper cups. Some consumers report that when using paper cups to hold hot water above 60℃, the inner coating may dissolve, especially with inferior paper cups made from industrial aluminum foil, where the amount of dissolved coating increases by 5 times. A milk tea shop in Guangxi was once complained about due to lead levels in its paper cups exceeding the standard by 11 times, leading to symptoms of lead poisoning in customers.

2.2 Cold Beverage Scenario Complaints
Complaints in cold beverage scenarios mainly focus on the anti-permeability and structural integrity of paper cups wholesale. Cold beverages are usually between 0℃ and 10℃, and when there is a large temperature difference with the external environment, a large amount of condensation will form on the outer wall of the paper cup, which places higher demands on the waterproof performance of the paper cup.
Complaints in juice scenarios mainly involve the hygiene and printing quality of paper cups. Consumers report that some paper cups wholesale develop an unpleasant odor after holding juice, especially those made from recycled pulp, which may contain harmful substances. In addition, the acidic nature of the juice may cause the inner coating of the paper cup to peel off, affecting the taste of the beverage.
Complaints in iced coffee scenarios focus on the water resistance of paper cups. According to professional analysis by paper cup manufacturer MTPak, paper cups are not the best container choice for cold drinks because the condensation from cold drinks can cause the paper cups to disintegrate in the consumer's hands. Especially in hot summer environments, a large number of water droplets form on the outer wall of iced coffee cups, causing the cup to soften and the labels to peel off, seriously affecting the user experience.
Complaints in carbonated beverage scenarios mainly involve the pressure resistance and sealing performance of paper cups. Carbonated beverages contain a large amount of carbon dioxide gas, which will produce bubbles after opening, challenging the sealing performance of the paper cup. Some consumers report that using paper cups wholesale to hold carbonated beverages easily leads to spillage due to overflowing bubbles, especially during transportation.

2.3 Complaints in Special Beverage Scenarios
Complaints in special beverage scenarios often involve compatibility issues between custom-printed paper cups and the characteristics of the beverages. Although these complaints are relatively few, the problems are quite complex.
Complaints regarding beverages containing fruit pulp mainly focus on the structural design and material selection of the paper cups. Ingredients such as tapioca pearls, nata de coco, and pudding in milk tea may cause uneven weight distribution in the cup, increasing the risk of spillage. One consumer complained that they found a large amount of flocculent and lumpy substances in the double-flavored milk tea (tapioca pearls + nata de coco) purchased from Yihetang, suspecting it was related to the paper cup material. Furthermore, beverages containing fruit pulp have higher viscosity, which may make cleaning the paper cups difficult, and residual substances can easily breed bacteria.
Complaints regarding alcoholic beverages mainly involve the chemical stability of the paper cup material. Although paper cup product standards explicitly advise against using paper cups to hold alcoholic beverages, some consumers still use paper cups wholesale to hold low-alcohol beverages such as beer and wine at parties and other occasions. Alcohol may cause the inner coating of the paper cup to dissolve, producing odors or migrating harmful substances.

III. Analysis of Paper Cup Quality Problem Complaints
3.1 Leakage Problems
Leakage is the most serious and common problem in consumer complaints about paper cup quality, directly affecting safety and user experience.
Bottom leakage is the most common form of leakage, mainly manifested as cracking or poor sealing at the seam between the cup bottom and the cup body. According to product recall information from the State Administration for Market Regulation, in November 2025, Huai'an Zhuomei Packaging Technology Co., Ltd. recalled its 750mL paper bowl products due to poor leakage performance. When holding high-temperature liquid food, leakage easily occurs, posing a safety hazard of scalding consumers. Consumers reported that some paper cups wholesale show noticeable water stains at the bottom after holding liquids, which gradually expand over time, eventually leading to complete leakage.
Seam leakage is another common form of leakage, especially at the vertical seam of the cup body. Complaint cases from Tim Hortons in Canada show that many consumers' paper cups disintegrate or leak at the seam between the body and the bottom. Some cups become saturated at the bottom within 10-15 minutes of purchase and suddenly open at the vertical seam, causing the entire drink to spill. This problem is closely related to the paper cup manufacturing process, mainly due to weak bonding at the seams or insufficient paper fiber strength.
While leakage from the rim is relatively less frequent, it severely affects the user experience when it does occur. Consumers report that some paper cups easily spill liquid from the rim, especially during drinking. This is mainly due to improper rim rolling, resulting in an uneven rim or poor sealing performance.

3.2 Cup Body Deformation Problems
Cup body deformation is the second most common quality problem reported by consumers, mainly manifested as various deformation phenomena caused by insufficient cup body rigidity.
Compression deformation is the most common deformation problem. According to product recall information, the paper cups wholesale recalled by Wuxi Xinlefan Paper Products Co., Ltd. had defects such as insufficient cup body rigidity and easy compression deformation. When filled with water or beverages, the cups would deform when lifted, and if filled with boiling water, it could easily cause burns to consumers. Consumers report that some paper cups undergo significant deformation during handling, severely affecting ease of use.
Thermal deformation is a special problem in hot beverage scenarios. When paper cups contain hot beverages above 85℃, the cup body will soften and deform in a short time. According to test data, insufficient cup body rigidity led to a 15% annual increase in complaints about burns from 90℃ hot water spills. A chain restaurant company optimized the rigidity of its paper cups, increasing the heat resistance temperature to 95℃, and the customer complaint rate dropped from 12% to 0.8%, fully demonstrating the importance of rigidity to product quality.
Cold deformation mainly occurs in cold beverage scenarios. When paper cups contain cold beverages, the thermal stress caused by the temperature difference between the inside and outside can cause the cup body to shrink and deform. Especially when containing drinks with a lot of ice cubes, the direct contact between the ice cubes and the cup wall accelerates the deformation process of the cup body.

3.3 Paper Strength Issues
Paper strength directly affects the lifespan and safety of paper cups wholesale and is a core quality indicator of concern to consumers.
Tearing problems mainly manifest as the cup body being easily torn or damaged. According to a survey by the International Food Packaging Association, 11 out of 25 paper cup samples tested had insufficient cup body stiffness, with some products having severely inadequate paper strength, easily tearing with a slight pull. This problem is particularly prominent during transportation and storage, often leading to damage to entire boxes of paper cups.
Insufficient bottom support is a major cause of paper cups wholesale tipping over. Consumers report that some paper cups, after being filled with liquid, do not provide sufficient support at the bottom and are prone to tipping over, especially when placed on uneven surfaces. A quality analysis report from the Baoting County Market Supervision Bureau points out that using low-quality pulp with low fiber strength or insufficient additives, such as wet-strength agents, can lead to insufficient cup body stiffness.
Insufficient wet strength is a key factor affecting the durability of paper cups. High-quality paper cups should have good wet strength, maintaining a certain structural strength even after absorbing water. However, some low-priced paper cups soften rapidly after absorbing water, rendering them unusable. This problem is even more pronounced when holding food with high water content.

IV. Analysis of Complaints Regarding the Sanitary Condition of Paper Cups
4.1 Odor Problems
Odor problems are a major focus of consumer complaints regarding the sanitary condition of paper cups wholesale, involving multiple aspects such as raw material selection, production processes, and storage conditions.
Ink odor is the most common odor problem. According to consumer warnings from the Sichuan Provincial Administration for Market Regulation, if manufacturers use inferior materials or poor-quality ink during production, the custom-printed paper cups will emit a pungent ink smell. Sampling results from the Suzhou Market Supervision Administration showed that 30% of the printing inks tested contained excessive levels of cyclohexanone and toluene. These substances are insoluble in water but can be released in hot water and enter the body through respiration. Consumers reported that some paper cups have a noticeable ink smell upon opening, and the smell becomes even stronger after holding hot beverages.
Raw material odors mainly originate from recycled pulp or inferior additives used in the paper cup production process. Some companies use recycled pulp to produce paper cups to reduce costs; these recycled materials may contain various chemical residues, producing unpleasant odors. Consumer warnings from the Inner Mongolia Institute of Quality Inspection point out that inferior materials or poorly printed inks may contain harmful substances such as benzene and toluene, causing the paper cups to emit a pungent odor.
Storage odors are caused by improper storage conditions. Paper cups are often stacked together for storage; if the storage environment is damp or contaminated, mold can easily form, emitting a musty smell. Consumers reported that some paper cups have a noticeable musty smell after opening the packaging, mainly due to moisture during storage.
