The Cardboard Sandwich Box produced by Qingchen Factory is an integrated visual food packaging container specifically designed for bakeries and light food cafeterias. Unlike single-uncovered paper trays or fully sealed flip-top lunch boxes, it adopts a combination structure of a cardboard base tray and a detachable high-transparency PET top cover. This design not only allows for the complete display of sandwich, rice balls, and salad ingredients, but also effectively prevents dust and retains moisture. It is suitable for both offline display and online food delivery channels.
When Qingchen Factory produces China Cardboard Sandwich Boxes, the bottom tray is made of two types of food-grade raw
cow cardboards with weights of 290g and 337g. They are formed as a single piece through a heat-pressing composite
process. The inner wall is equipped with a food-water-based anti-oil layer, without any additional plastic coating, and
is biodegradable. It is also accompanied by a hard PET transparent cover that fits tightly and does not fall off,
completely enclosing the food without spilling any ingredients.
Our advantages
The factory always has 6 sets of standardized ready-made sizes in stock, covering everything from single-person mini
sandwiches to large portions for multiple people to share; at the same time, it supports full-dimensional customization,
capable of performing processes such as CMYK four-color printing, embossing, gold stamping, matte coating, etc., with
only the outer layer of printing not touching the food. The entire product range is produced in the dust-free food
workshop in Zhejiang and holds SGS and FDA food contact inspection reports. It can provide stable supply for both
replenishment in domestic stores and cross-border baking packaging and foreign trade orders.
Core performance
1.Food compliance and safety performance
Our Cardboard Sandwich Box has passed SGS testing and complies with FDA food contact standards. The original kraft paper contains no fluorescent whitening agents or recycled waste materials. The ink is only printed on the outer layer of the box. Food for raw consumption, room-temperature baking, and microwave heating can be directly contained. No harmful substances will be released.
2.Long-lasting oil and water resistance protection
The inner wall has a heat-synthesized oil-resistant layer. Salad sauce, mayonnaise, and fruit juice will not penetrate the paper surface even after standing still for 4 hours, and there will be no problem of the bottom of the box becoming soft or leakage and dirtying the takeout bag; the paper body will not easily separate or be damaged when exposed to clean water for a short period of time.
3.Wide temperature and weather resistance compatibility
Stable tolerance - from -20℃ refrigeration to 120℃ microwave short-time heating range. Cold storage of rice balls and cold sandwiches will not crack; it can be directly placed in the microwave for short-time reheating without the need to replace the container.
4.Load-bearing and compressive structure performance
The heat-pressed integrated folding edge process provides sufficient support for the side edges of the box. Even when filled with multi-layer thick-cut sandwiches stacked for delivery, it will not collapse inward. The bottom can stably bear a load of 1.6L water weight, and it will not deform during long-distance delivery with stacking.
5.Transparent cover for visual display performance
The high-transparency PET cover has no foggy or blurry flaws. Customers can clearly see the internal ingredients without opening the cover, enhancing the store display appeal; the cover is designed to fit the slot, and it will not loosen or shift even during riding bumps or multi-layer stacking.
6.Environmental protection and degradable performance
The kraft paper base material can be fully recycled and degraded. The PET cover can be classified for recycling. There is no non-degradable composite layer. It complies with the plastic restriction policies of both domestic and overseas catering industries, and there will be no obstacles for environmental audits in markets, supermarkets, export customs clearance.

FAQ
Q1: Can the wax paper tray be used alone without the PET cover?
A: Yes, the tray itself is an independent structure. Without the cover, it can be used for table setting; when combined with the PET cover, it can achieve dust-proof and spill-proof functions for delivery. Both usage methods can be freely combined for purchasing.
Q2: Is it necessary to remove the transparent PET cover when using microwave heating?
A: It is recommended to remove the PET cover before microwave heating. The PET plastic will deform under long-term high temperature, and the wax paper tray can be directly reheated for short-term microwave cooking of the meal.
Q3: How do the 6 standard sizes of the cardboard sandwich box correspond to different types of food?
A: The small size QC-N1001/1002 is suitable for mini triangular sandwiches and small rice balls; the medium size 1003/1004 is suitable for regular toast sandwiches; the large size 1005/1006 is suitable for thick-cut multi-layer toast and double-person sharing platters.
