Plastic cups for events
Plastic cups are a versatile option for events, offering a range of benefits depending on their intended use. They are available in various sizes, styles, and thicknesses, making them suitable for different beverages and occasions. Here are some key considerations when choosing plastic cups for events:
Disposable vs. Reusable Cups
A key decision when selecting plastic cups for events is whether to opt for disposable or reusable cups. Disposable cups are economical and convenient, especially for large events or occasions with high drink service expectations. They are typically made from thin, flexible plastic, which makes them cheap and easy to use but limits their durability. These cups are intended for single-use and should be responsibly recycled. In contrast, reusable cups are thicker and more durable, offering the advantage of multiple uses. They are often found at events where people either return the cup or dispose of it in a recycling bin. Reusable cups made from double-walled plastic are bulkier and more expensive but excel at maintaining beverage temperatures without compromising hand comfort.
Compostable Cups
Compostable plastic cups are an environmentally conscious alternative to traditional disposable cups. These cups are made from plant-based materials and are designed to break down in commercial composting facilities. They are well-suited for events that value sustainable practices but may have minimal disposal options. Compostable cups are available in various colours and designs, allowing for uniform or themed looks to match the event's nature.
Customisation
Customising plastic cups with event logos, texts, or other designs can add a personal touch to your event and serve as a memorable souvenir for attendees. This customisation option is available for both disposable and reusable cups and can be an effective marketing technique to increase brand visibility.
Size and Beverage Type
Durability and Temperature Considerations
The thickness and material of plastic cups impact their durability and temperature suitability. Polypropylene (PP) cups are strong and suitable for warmer temperatures, making them an excellent choice for hot beverages. Polystyrene (PS) cups are softer and more affordable, while polyethylene terephthalate (PET) cups are clear and valued for their recyclability. Thicker versions of these materials will enhance the cup's sturdiness, preventing bending or warping under heat or pressure. For events with a wide range of beverages, consider cups with temperature tolerance, such as those made from PLA corn plastic, which can withstand temperatures from 40 to 105 degrees Fahrenheit.

Reusable plastic cups
Plastic cups are used for a wide range of applications, from serving smoothies to coffee. Plastic cups can be disposable or reusable. Reusable plastic cups are considerably thicker than disposable cups, which are made from very thin plastics. Reusable cups are also more expensive than single-use cups. They are found at events where people either return the cup or toss it in a recycling bin.
Double-walled plastic mugs are thicker than most other types of plastic cups and offer heat protection. They are bulkier and more expensive than other cups. They are good at keeping beverages at their desired temperature for longer while protecting hands from heat or cold.

Single-use plastic cups
The thickness of plastic cups varies depending on their intended use. For instance, thicker plastic cups, often termed with a gauge like 12-16 G, offer more strength and endurance, making them suitable for hot foods or hazardous situations. These thicker cups are ideal for holding hot beverages, as they provide heat protection and keep drinks warm for longer. They are also less likely to bend or warp under heat or pressure.
On the other hand, thinner plastic cups are designed for light-duty tasks and cooler conditions. These cups are often used for samples or in situations where durability is less of a concern. Thinner cups are more susceptible to bending or warping and are not suitable for hot beverages.
The type of plastic used also affects the thickness of single-use plastic cups. Common plastics used include polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET). Polystyrene is a softer and cheaper option, while polypropylene is stronger and can withstand warmer temperatures. Polyethylene terephthalate (PET) is valued for its clarity and recyclability.

Plastic cups for hot drinks
Plastic cups are a popular choice for serving hot drinks such as coffee, tea, and cocoa due to their convenience. However, there are concerns about the safety of using plastic cups for hot beverages, as certain plastics can release chemicals into the drink when exposed to high temperatures. This includes bisphenol A (BPA), which has been linked to health issues such as hormonal disruptions and an increased risk of certain cancers. Other chemicals like phthalates and styrene can also leach into drinks, especially if the cup is not designed for high temperatures. Therefore, it is recommended to use cups specifically designed for hot liquids, such as those made of polypropylene (PP), which has a higher melting point and better heat resistance than other plastics. These cups are commonly found in coffee shops and cafes and offer superior heat management for hot beverages. They also provide effective thermal insulation, maintaining the drink's temperature while keeping the exterior surface comfortable to touch.
Polystyrene (PS) cups, on the other hand, are often used in fast-food restaurants and vending machines. They are lightweight, durable, and have good insulating properties. However, a study by the European Food Safety Authority found that when polystyrene cups were exposed to hot liquids at 70°C for two hours, there was a significant increase in chemical leaching. Therefore, it is recommended to allow hot drinks to cool slightly before pouring them into polystyrene cups and avoid reusing these cups for hot drinks to minimise the risk of chemical leaching.
Another option for hot drinks is polyethylene terephthalate (PET) cups, which are known for their clarity and recyclability. While they may not have the same heat resistance as polypropylene cups, they can still be used for hot beverages if designed for high temperatures.
To summarise, while plastic cups offer convenience for hot drinks, it is important to choose those specifically designed for hot liquids to ensure safety. Polypropylene cups are a popular choice due to their superior heat resistance and thermal insulation properties. Polystyrene cups are also widely used but come with a higher risk of chemical leaching at high temperatures. Reusable cups made of alternative materials like stainless steel, glass, or ceramic can be safer alternatives for hot drinks, reducing waste and potential health risks associated with plastic.

Plastic cups for cold drinks
For outdoor events or activities where the cups need to be break-resistant and withstand varying temperatures, high-thickness cups are ideal. These cups usually have a thickness of about 1 millimetre and are made from materials such as polystyrene or polypropylene, making them suitable for both hot and cold drinks. Their durability also makes them less likely to break at outdoor events. Additionally, thicker cups are often preferred in restaurants, catering services, and beverage stores as they can be reused multiple times before recycling. These cups are typically made from recyclable and plant-based materials such as polycarbonate (PC) and polylactic acid (PLA).
The design of plastic cups for cold drinks also varies in size, shape, colour, and decoration, with some thicker cups incorporating insulating walls to minimise heat transfer when containing hot beverages. Cups with smooth or rolled rims are also available and can come in various styles, sizes, and shapes to suit different beverages and occasions. For example, polystyrene cups are commonly used for cold beverages and are known for their sturdiness, shatter resistance, and flexibility. Compostable plastic cups made from PLA corn plastic are another option, offering complete product visibility and an environmentally friendly alternative to traditional plastic cups.
It is important to note that plastic cups for cold drinks are designed specifically for that purpose, and using them for hot drinks can have negative consequences. Hot liquids can cause the walls of the cup to break down or melt, leading to leaks and spills. Additionally, hot drinks in cups designed for cold beverages can cause burns if the cup becomes too hot to handle. Therefore, it is recommended to use cups designed for their intended temperature to ensure safety and maintain the optimal temperature of the beverage.
