Q1: How do I choose paper thickness for a sandwich wedge?

A thicker paper is not always better; the right thickness depends on the sandwich weight, filling, and handling conditions. For a sandwich wedge, we evaluate product size together with filling density, grease or moisture levels, stacking pressure, and delivery conditions. A heavier sandwich or one with wet, oily fillings may need a stronger paper structure. For lighter products used in short-distance takeaway, a lighter specification may be sufficient. We recommend testing the actual sandwich in the proposed sandwich box before mass production. This helps confirm fit, rigidity, and handling performance without adding unnecessary material cost.

Q2: Should I choose PE or PLA lining for sandwich packaging?

PE is usually the practical choice for standard grease and moisture protection, while PLA can be considered when a plant-based material direction is preferred and suitable for the application. The choice depends on the sandwich ingredients, holding time, temperature, and expected handling conditions. For products containing sauces, cheese, meat, or other moist fillings, the lining should be evaluated for the actual food contact conditions rather than selected only by material preference. For sandwich packaging, we recommend confirming the food characteristics and operating environment first, then selecting the lining and paper combination that provides the required protection.

Q3: Is a PET window suitable for my sandwich packaging?

Yes, a PET window is suitable when product visibility is important and the package structure can accommodate the window correctly. For a sandwich container, we consider the sandwich shape, filling height, window position, and viewing angle when developing the structure. The window should provide clear visibility without interfering with folding, closing, or product placement. For grab-and-go and retail applications, visibility can also make it easier for customers to identify the sandwich without opening the package. We recommend confirming the actual food dimensions and display method before finalizing the window size and position.

Q4: Can you make a sandwich wedge around our actual food dimensions?

Yes, custom sandwich wedge packaging can be developed around the actual food dimensions. A proper fit requires more than the sandwich's length and width; filling height, product thickness, shape variation, and packing method also affect the internal dimensions. If the package is too tight, it may compress the food or make packing difficult. If it is too loose, the sandwich may move during delivery and lose its presentation. We recommend providing accurate food measurements or a physical sample for structural development. We can then evaluate the dimensions and adjust the wedge structure before mass production.
