Shrink Sleeving Machine Decoration for Plain Empty Dairy Cup

In this case sharing, we will explore how our shrink sleeve applicator machine was used in a project focused on decorating plain empty dairy cups or other cup-shaped packaging. Our cup shrink sleeving machine is designed to cater to various industries, including dairy processing plants, packaging container suppliers, ready-to-eat food packaging decoration, and stocking distributors. Our versatile sleeving machine ensures that products can be decorated regardless of container or cup shape and without limitations on custom quantities. Here’s how our solution provided value and overcame specific challenges in this project.

Specific Case Study for Plain Empty Dairy Cup

This shrink label machine project involves applying shrink film onto empty round and square plastic cups.
Our shrink sleeve applicator was deployed in a dairy processing plant to decorate plain empty dairy cups. The goal was to apply shrink sleeve labels to enhance the product’s appearance and branding. The versatility of our cup sleeve machine allowed it to handle different cup shapes and sizes efficiently.

Analysis of Empty Plastic Dairy Cups

When we get all the details of the specific cups, we provide a detailed analysis of empty plastic cups based on different materials, shapes, and opening sizes. Combining this analysis with the customer’s production speed requirements, we recommend the most suitable shrink sleeving solution.

Cup Materials

PP (Polypropylene): Lightweight, durable, and widely used in food packaging. Suitable for high-speed production but may require precise temperature control to prevent warping.
PS (Polystyrene): This rigid and clear material is often used for yogurt cups. It requires careful handling in shrink tunnels to avoid cracking.
PET (Polyethylene Terephthalate) is strong and impact-resistant, and it is commonly used for beverages. It is ideal for high-speed lines and can handle higher shrink temperatures.

Cup Shapes

Cylindrical: Easiest to label with shrink sleeves due to uniform shape.
Tapered: Requires precise application to ensure even shrinkage along the taper.
Square/Rounded Corners: More challenging due to the potential for uneven shrinkage at corners.

Opening Sizes

Wide Mouth: Common in dairy cups, necessitates careful alignment of the shrink sleeve to ensure it adheres without wrinkling or slipping.
Narrow Mouth: Less common but requires accurate application to avoid excess material gathering at the top.

As a professional and responsible manufacturer, we suggest that you ask more questions before deciding to buy the machine.If possible, the best way is to send your samples to the machine supplier and ask them to test the product for you and check it first for free.

Recommended Shrink Sleeving Solution

Based on the analysis of the cup materials, shapes, and opening sizes, and considering the production speed requirements of the customer, we recommend the following shrink sleeving solution:

Customized Electric Heat Shrink Tunnel: Designed specifically for empty plastic cups to operate at lower temperatures, preventing deformation. This tunnel can handle high-speed production without compromising on quality.
High-Precision Applicators: Ensuring that the shrink sleeves are applied accurately and tightly, regardless of the cup shape and opening size.
Material Selection: Using suitable shrink films for their high shrinkage properties and environmental benefits, ensuring a perfect fit and attractive finish on various cup shapes.

To prevent the deformation of the empty plastic dairy cups, we had to shrink the sleeves at a lower temperature. However, this lower temperature was insufficient to achieve the desired shrinkage in the electric heat shrink tunnel. To address this, we extended the length of the electric heat shrink tunnel, allowing the shrink labels to continue shrinking in the additional section until the perfect shrinkage effect was achieved, ensuring the empty plastic dairy cups remained undamaged. Our recommendation is backed by our extensive experience and professional technical analysis.

Challenges in Decorating Empty Plastic Cups by Shrink Sleeving Machine

Decorating empty plastic cups with shrink sleeves presents unique challenges:

Label Slippage: Shrink sleeve labels might not adhere tightly to the cup surface, risking slippage. To combat this, we used high-precision applicators and selected the appropriate shrink film to ensure a snug fit.
Heat Distortion: Using an electric heat shrink tunnel at high temperatures can deform empty plastic cups. To prevent this, we customized an electric heat shrink tunnel specifically designed for empty cups. This tunnel operated at lower temperatures while maintaining efficient shrinkage, avoiding any deformation.

In Conclusion

This project demonstrated our machine’s flexibility and effectiveness in decorating plain empty dairy cups with shrink sleeve labels. By carefully selecting the label material, customizing the shrink tunnel, and ensuring machine compatibility, we delivered a solution that met the client’s needs and overcame common challenges in the process. For businesses looking to invest in shrink sleeve applicators, our case studies offer valuable insights and underscore our commitment to providing practical, efficient, and customized solutions.
