高バリア包装フィルム&食品グレードトレイ
Ordinary low-barrier plastic films have poor oxygen and water vapor isolation performance, which cannot block external air penetration and will lead to food deterioration in a short time. High-barrier packaging films have excellent oxygen resistance, moisture resistance, and antibacterial properties, which can maintain a stable internal packaging environment for a long time. Cooperated with food-grade PP, PET, and aluminum foil trays that meet safety standards, they avoid chemical precipitation and ensure food safety while achieving efficient barrier fresh-keeping.
It is necessary to select corresponding barrier materials according to food attributes: high-fat cooked food needs oil-resistant and high-temperature resistant high-barrier films, while fresh fruits and vegetables need breathable and anti-fog high-barrier materials to adapt to their breathing characteristics.
MAP、冷蔵·冷凍保管との互換性
All selected trays and films must have good MAP gas compatibility and low-temperature resistance. Special materials for modified atmosphere packaging can maintain stable sealing performance and barrier effect after gas replacement, avoiding gas leakage and failure of fresh-keeping effect. Meanwhile, for food stored in refrigeration (0–4℃) and freezing (-18℃) environments, low-temperature resistant packaging materials must be used to prevent film embrittlement, cracking, and tray deformation in low-temperature environments, which cause sealing failure and shelf-life shortening.
正しいシーリング変数
Even with high-quality materials, unreasonable sealing parameters will lead to defective packaging and fail to achieve fresh-keeping goals. Accurate temperature, pressure, and time setting is the key to perfect sealing.
温度、圧力、ドウェル時間の設定
The three core parameters of tray sealing are mutually restricted and need to be adjusted according to film thickness and tray material. Excessively low temperature, insufficient pressure, or too short dwell time will cause weak bonding of the film and tray, resulting in poor tightness. On the contrary, excessively high temperature and overlong dwell time will burn the film edge, cause material deformation, and affect the appearance and barrier performance.
Standard operation requires pre-testing parameter debugging for different packaging combinations to formulate exclusive sealing schemes, ensuring firm, flat, and non-deformable sealing edges.
漏れ、しわ及び不完全なシールを防ぎます
Common sealing defects such as edge wrinkles, local incomplete sealing, and tiny leaks are invisible killers of food shelf life. Even micro gaps will cause continuous air penetration and bacterial invasion, leading to food spoilage in advance. In daily production, it is necessary to keep the sealing mold flat and clean, accurately position the tray and film, and avoid deviation and wrinkles during pressing. Regularly inspect sealing effects to eliminate all hidden dangers of incomplete sealing.
| Tray & Film Material Type | Sealing Temperature (℃) | Sealing Pressure | Dwell Time (s) | Applicable Scenarios |
| Standard PP Tray + Normal PE Film | 160–180 | Medium | 1.0–1.5 | General ready meals, dry snacks, room-temperature storage |
| PET Tray + High-Barrier Film | 175–195 | 中～高 | 1.5–2.0 | Refrigerated food, fruits, vegetables, common MAP packaging |
| Thickened PP Tray + Oil-Resistant Film | 185–205 | 高い | 2.0–2.5 | High-fat cooked food, fried products, heat-resistant packaging |
| Frozen Food Tray + Low-Temp Resistant Film | 155–170 | Medium | 1.0–1.8 | Frozen meat, frozen pre-made meals, low-temperature storage |
| Biodegradable Tray & Film | 145–160 | Medium-Low | 1.8–2.2 | Eco-friendly packaging, light-weight fresh food |
Note: The above data is for standard reference only. Actual parameters should be fine-tuned according to film thickness, equipment model, and workshop environment to achieve flat, wrinkle-free, and leak-proof sealing.
