An integrated covered packaging solution designed specifically for fragile, high-value cookies, brownies, and desserts. The tray is made of high transparency PET material and molded by precision plastic absorption process. The double grid large capacity design perfectly matches the standard size Dim sum. Innovatively adding reinforcing ribs on the side significantly improves the overall compressive and stacking strength. Paired with a high transparency PET cover, it achieves a comprehensive functional upgrade from display, protection to sealing.
Q: What is the specific function of "reinforcing ribs" on the side?
A: Reinforcing ribs are specially designed protrusions or striped structures on the side of containers. Its core function is similar to the "load-bearing column" in architecture, which can greatly enhance the container's:
Stress resistance: prevents being crushed when stacked or subjected to external pressure.
Anti deformation ability: ensure that it is not easy to bend and crack during transportation, and protect the integrity of the internal Dim sum.
Stacking stability: making the upper and lower containers bite more firmly during stacking, and less likely to slide.
Q: Can the lid be completely sealed?
A: This design usually adopts the form of a buckle or friction cover, which can achieve good dustproof and moisture-proof effects, and prevent the cover from accidentally opening. If you need a completely leak proof seal (for example, for Dim sum containing syrup), we can evaluate the feasibility of upgrading to a heat sealing film, but this requires adjusting the design of the lid.
Q: Can trays be used for microwave heating?
A: Not recommended. Although PET is a food grade material, the heat-resistant temperature of ordinary PET trays is usually below 70 ℃ and is not suitable for microwave heating. Its main functions are packaging, display, and transportation.
Q: Can this covered PET tray be used for microwave heating?
A: Strongly not recommended. Although PET is a food grade material, ordinary PET material has limited heat resistance (usually below 70 ℃) and is not suitable for microwave ovens. The lid may also deform due to high temperature. Its main functions are packaging, display, and transportation protection.
Q: Can the size or shape of the compartments be customized?
A: Of course you can. This is the core value of customized services. If you have special product sizes or want to create a unique brand shape (such as heart shape, circular grid), we can customize vacuum forming molds for you to ensure a perfect fit for your product.
