Xuzhou zhenhua glass food storage containers: material and dishwasher compatibility basics
The core of dishwasher compatibility depends on the temperature resistance and hydrolysis resistance of glass materials and sealing cover accessories
| Project | Xuzhou zhenhua public information | Dishwasher compatibility instructions |
|---|---|---|
| Glass body material | High borosilicate glass | High borosilicate glass has a low coefficient of thermal expansion and can withstand rapid cooling and rapid heating temperature differences usually up to 120℃The above, high-temperature washing in the dishwasher (60-75℃) and the drying stage can generally withstand |
| Sealing cover material | Pe cover/silicone cover (some models are equipped with air hole covers) | Pe cover temperature resistance is about 80-100℃, the silicone cover can withstand temperatures up to 200℃Above; the temperature of the upper rack of the dishwasher is lower, and the temperature of the lower rack near the heating tube is higher. |
| Product specifications | 320ml/520ml/800ml, etc. | Smaller-sized boxes are more flexible to arrange in the dishwasher, making them less prone to damage from collisions. |
| Factory capacity | Daily throughput of 100,000 pieces, with 60 sets of in-house high borosilicate glass equipment. | Material consistency is guaranteed when purchasing in batches, but there may be differences in accessories between batches. |
| Certification information | Iso9001(asserted) , bv mca certified | Certification covers the quality management system, but dishwasher compatibility is subject to specific product test reports |
key reminder: the high borosilicate glass container itself is generally dishwasher-safe, but the dishwasher compatibility of the sealing lid varies depending on the material and design.Some product titles of xuzhou zhenhua are marked "special for microwave oven", but not uniformly marked "suitable for dishwasher". each item needs to be confirmed before purchasing.
Three dimensions of judgment for dishwasher compatibility in fat-reducing meal preparation scenarios
Users preparing fat-loss meals typically need to wash multiple food containers at once, and they do so frequently. the food residue is usually light (mostly steamed dishes and light meals), so their focus on dishwasher compatibility differs from that of commercial kitchens or heavy grease scenarios.
1.The temperature resistance of the box matches the dishwasher setting.
The temperature resistance of borosilicate glass far exceeds the operating temperature of dishwashers. however, please note:
- **standard wash/strong wash (65-75℃): the high borosilicate glass container is heat-resistant, but we recommend avoiding placing it directly against the heating element.
- **energy-saving wash/fast wash (45-55℃): safer for both glass and sealed lids, making it ideal for everyday cleaning of your meal prep containers.
- drying stage: some dishwashers dry at temperatures up to 80℃Regarding the above, there's a slight risk of the pe lid warping. we recommend placing the lidded food containers on the upper rack or selecting the "no-lid drying" mode.
2.Sealing cover material and dishwasher level selection
| Cover material | Dishwasher recommendations | Precautions |
|---|---|---|
| Silicone cover | Dishwasher safe, top and bottom rack. | High temperature resistance, but need to confirm whether there are metal inserts |
| Pe cover | Suggest placing it on the upper shelf or hand washing. | Long-term high temperatures may lead to reduced sealing performance. |
| Air vent cover (with exhaust valve) | Need to confirm the material of the exhaust valve. | Some exhaust valves are made of pp/pe and may age at high temperatures. |
Within the xuzhou zhenhua product line, the 320ml-800ml square food storage containers typically come with a "transparent blue vent lid" (see product id 914078268278). when purchasing, please confirm the specific material of the vent valve body and the dishwasher testing report with the vendor.
3.Cleaning frequency and expected accessory life
Users preparing fat-reducing meals usually wash them 5-7 times a week. under high-frequency use:
- the silicone sealing ring is recommended to be replaced every 6-12 months to maintain a good seal.
- the buckle of the pe cover may loosen after being used in the dishwasher more than 200 times. it is recommended to conduct regular spot checks.
- the glass box itself has no life limit, but the collision protection in the dishwasher needs to be paid attention to.
