Specific Cases for Empty Yogurt Cup
— Essential Details You Should Know Before Purchasing
We have done a lot of projects for empty yogurt cups, and we have summarized some of the difficulties and details that need attention in the project.
1. Which shrink tunnels will be chosen for shrinking labels on empty yogurt cups?
Based on our experience, almost all customers will choose the electric shrinking tunnel to be used in the empty yogurt cup sleeve labeling machine instead of selecting the steam shrink tunnel, which has always been good in shrinkage performance, due to the potential issues associated with moisture entering the cups during the shrinking process.
Moisture steam can condense and adhere to the cup’s surface and inside, leading to the growth of mold or bacteria over time. The moisture cups pose a risk of cup contamination, making them unsuitable for food packaging.
Additionally, certain products require a dry and sterile processing environment, which cannot be achieved with steam shrink tunnels. Electric heat shrink tunnels are preferred in such cases as they provide dry heat without introducing moisture, ensuring a clean and hygienic packaging process. Considerations of cup cleanliness, hygiene, and the need for a dry and sterile environment make electric heat shrink tunnels the recommended option for achieving optimal shrinkage on empty yogurt cups.
2. What kind of electric heat shrink tunnel is suitable for empty yogurt cups?
As we know, Yogurt cups are typically made of food-grade plastic materials such as polypropylene (PP) or polystyrene (PS). These materials are widely used in food packaging because they are lightweight, durable, and resistant to moisture and temperature changes. But due to their light and special shape o size, the standard electric shrink tunnels are unsuitable for empty yogurt cups.
We have designed an electric shrink tunnel specially used for empty yogurt cups. Its 360-degree circulating hot air system makes the sleeve label heated evenly, producing a good shrink effect.
Its remarkable feature is that it can recycle the hot air in the tunnel so that the temperature will not be too high, and the empty cup won’t be deformed by high temperature.
potential difficulties when labeling on empty yogurt cup
Sleeve labeling machines can be used on empty plastic cups for sleeve labeling purposes. However, there can be some considerations and potential difficulties when using sleeve labeling machines on empty plastic cups:
1. Cup Material: The material of the plastic cup plays a role in the labeling process. Some plastic cups may have a surface incompatible with sleeve labels or require special treatment to ensure proper adhesion of the shrink sleeve label.
2. Cup Shape and Size: The shape and size of the cup can affect the labeling process. Irregular cup shapes or cups with curves, ridges, or tapered designs may require customized label designs or additional adjustments to ensure the label wraps around the cup smoothly and without wrinkles or gaps.
3. Cup Stability: The stability of the cup during the labeling process is important to achieve accurate and consistent label placement. Cups that are lightweight or tend to tip over may require additional measures, such as specialized fixtures or equipment, to ensure proper alignment and label application.
4. Production Speed: The sleeve labeling machine’s production speed must be compatible with the required output and production line speed. High-speed production needs a high-quality electric shrink tunnel and more sets of tunnels.
By working closely with a reputable sleeve labeling machine manufacturer and providing the necessary details about the cups, such as material, shape, and size, they can offer guidance and provide customized solutions to address any difficulties or challenges in labeling empty yogurt cups.

— PP (polypropylene) and PS (polystyrene)
Yogurt cups are mainly made of food-grade plastic materials, polypropylene (PP) or polystyrene (PS).
Both polypropylene (PP) and polystyrene (PS) are widely used in the food packaging industry and have been approved by regulatory agencies for safe contact with food. PP and PS are known for their durability, moisture resistance, and ability to withstand various temperatures, making them suitable for food containers, especially yogurt cups. However, ensuring that the specific PP or PS material used in food packaging meets the necessary safety and regulatory standards is always important.
- Polypropylene (PP): PP has a relatively high heat resistance compared to many other plastics. It can withstand temperatures up to approximately 160°C (320°F) before it starts to deform. This heat resistance makes PP suitable for various food packaging applications, including microwave-safe containers and dishwasher-safe products.
- Polystyrene (PS): PS has a lower heat resistance than PP. It can withstand temperatures up to approximately 70-80°C (158-176°F) before it begins to soften or deform. While PS is unsuitable for high-temperature applications, it is commonly used for cold or room-temperature food packaging, including yogurt cups and disposable cutlery.
It’s important to note that the heat resistance of PP and PS may vary depending on the specific grade and formulation of the plastic. Manufacturers often provide temperature guidelines for their particular PP or PS products.
