Ndi kukula kwa malonda azakudya, kufunidwa kwa ogula kwa "chitetezo" ndi "mosavuta" sikunakhalepo mwachangu. From the ready-to-eat lo-mei on the supermarket shelves to the hot-selling pre-made dishes on the takeaway platform, there is a seemingly ordinary but vital packaging material behind it –lembani thumba. This kind of packaging, which is characterized by high temperature resistance and strong sealing, not only greatly extends the shelf life of food, but also quietly changes the entire chain of food production, transportation and consumption.
Choyamba, maubwino apakati
Thumba lolembais unique in that it solves two major pain points of traditional packaging: it cannot withstand high temperature sterilization and has limited freshness preservation. Ordinary plastic bags are prone to deformation, cracking, and even release harmful substances at high temperatures, but Retort Pouch is cleverly designed with multi-layer composite materials to withstand boiling water for a long time while maintaining the integrity of the packaging. For example, after marinated duck neck, sauced beef and other cooked foods are sterilized at 100°C, the retort pouch can effectively isolate oxygen and moisture, prevent microbial growth, and keep the product at room temperature for several months without relying on cold chain transportation. Izi sizimangochepetsa mtengo womwe mabizinesi a bizinesiwo, komanso amalola ogula kuti akhale ndi chakudya chotetezeka komanso chosiyana kulikonse, kulikonse.
Kuphatikiza apo, thumba la revoctor limathandizira chidziwitso chabwino cha "kuyamwa motentha. Consumers do not need to open the package, and directly put the bag into boiling water or microwave oven (some applicable models) to heat, which not only avoids secondary contamination, but also retains the original taste of the food. This design is particularly suitable for the fast-paced life of modern times, making it ideal for pre-made dishes, instant soups and other categories.
2. Ntchito yogwiritsa ntchito: Kuchokera kulowera mumsewu Lo-Mei ku mbale zapamwamba kwambiri
Kusintha kwa thumba la revort kumawalola kuphimba zomwe zachitika pamwambapa kuchokera ku misika yazing'ono za mafakitale:
3. Kusiyanitsa
Retort pouch may seem similar to ordinary plastic bags, but in fact, there are significant differences in terms of material selection and production process. Kuti apange thumba labwino kwambiri, njira zotsatirazi ziyenera kuwongoleredwa:
1. Kusankha zakuthupi
Each layer of the Retort Pouch has a specific function: the outer layer needs to be abrasion and tear resistant, the middle layer blocks light and oxygen, and the inner layer must be safe, non-toxic and resistant to high temperatures. Zipangizo zopangira chakudya ziyenera kugwiritsidwa ntchito popanga, ndikubwezeretsanso zinthu kapena zowonjezera zotsika ziyenera kupewedwa. For example, if the temperature resistance of the inner material is insufficient, harmful substances may be released after cooking, leading to food safety risks.
2. Kuwongolera
Kupanga kwa zotsatsa za revor kumafuna kuwongolera kotheratu ndi kusasitsa. Zotsatira ziyenera kugwiritsidwa ntchito moyenera kuti zitsimikizire kuti zigawo za zinthu zikugwira mwamphamvu; Panthawi yochirikiza, ndikofunikira kukhalabe ndi kutentha komanso chinyezi kotero kuti guluuzo limachiritsidwa kwathunthu. If the curing time is reduced in order to shorten the construction period, it may lead to delamination and leakage of the package during high-temperature sterilization.

Matumba wamba apulasitiki amangofunika kuyeretsedwa mawonekedwe ndi kutsekedwa, pomwe makope a rector amafunika kudutsa mayeso owopsa. Mwachitsanzo, chomalizidwacho chimasunthidwa mu madzi otentha kwambiri kwa nthawi yayitali kuti muwone ngati pali kusokoneza ndi kutayikira; Dontho ndi kuyesa kumachitika phukusi kuti mutsimikizire kuti ndi kutsutsana. Makampani amafunikanso kupereka masinjidwe pafupipafupi kuti atsimikizire kuti zida zapamalo zimakwaniritsa zosowa za nyama.
