The invention is illustrated by the following examples, and is not limited thereto. The experimental part contains the preparation of the water-soluble unit (unit A ) of Gapdan

The water-soluble unit contains a chamber which encapsulates the Gapdan composition (Gapdan 80 WDG, Merpan), which is made by a vertical FFS machine, which forms a PVA bag (Aicello PT 40) and fills a certain amount Gap Dan (Merpan). Under vacuum, use hot rod welding or pulse welding to seal the water-soluble unit containing Gapdan. Example 1- Pack the water-soluble unit in a vacuum sealed bag.

Place unit A in a sealed bag (laminated three-layer foil PE/AL/PET (PlastoSac)).

Using pulse welding, the sealed bag was sealed under vacuum for 30 seconds. The vacuum degree in the sealed bag is less than 600 mmHg. Example 2- Pack the water-soluble unit in a sealed bag, which is sealed under ambient pressure.

Place unit A in a cross-linked PE zipper bag.

Seal the bag with a zipper. The pressure is environmental pressure. There is no vacuum in the sealed bag. Stability test:

Samples 1 and 2 are stored at 40°C for 8 weeks, and parameters such as (1) dissolution rate (starting to dissolve and fully dissolving), (2) sieve residue (filter and top sieve filter) and swelling are checked. Test 1, the dissolution time test under laboratory conditions, which is based on CIPAC MT 176

Hang the 10 cm ² thin PVA strips (taken from Examples 1 and 2, and from the fresh PVA thin layer, which has not been stored) on the metal hook with the plastic cover. 2. Subsequently, put the strips into a beaker containing 100 ml of standard hard water (500 ppm hardness, pH 7.0-8.0, Ca++:Mg++ = 4:1), and disperse Gapdan 80 WDG in it. The water temperature is maintained at 20°C or lower. 3. Keep the thin layer of tape inside the Gapdan dispersion for 10 minutes without stirring, and then stir for 10 minutes with a magnetic bar at a speed of 1500 RPM. 4. Pour the dispersion onto a 150 µm sieve and observe any residue. 5. Measure the time until the thin layer strip starts to dissolve. Example 1-Sealing under vacuum Example 2-Sealing at ambient pressure Fresh PVA thin layer Dissolution time-the time to start the thin layer dissolution of the chamber 30 seconds 4 minutes 30 seconds Residue at the end of the test Some flakes <1mm Many slices of 2-3mm No residue

The results show that the unit stored under vacuum (Example 1) is more stable than the unit not stored under vacuum (Example 2). The initial dissolution time of the thin layer of the chamber wall in Example 1 is the same as the fresh PVA strip tested under the same conditions. In addition, compared with Example 2, the amount of sieving residue in Example 1 is lower, indicating that the dissolution time of Example 1 is usually lower than Example 2. Test 2, field simulation test: Material:

A 1000 liter commercial can sprayer contains (50% volume) cold water at 5°C and commercial fertilizer, calcium chloride (180 grams), and magnesium chloride hexahydrate (80 grams). The water hardness is at least 342 ppm, Ca and Mg The molar ratio is 4:1 (PH is 7.9). test:

Step 1. Place the units of Examples 1 and 2 on the top sieve of the spray can.

Step 2. Apply cold running water (5°C) to the water-soluble unit placed on the top sieve under a pressure of 4 bar.

In the whole step 2, for each dissolution unit measurement, the time is in seconds, and the water volume is in liters.

In addition, the internal mixing nozzle and the filter are in operation mode, and the nozzle continues to agitate for 10 minutes.

Step 3. The resulting spray solution of Step 2 is applied with a rod-type sprayer equipped with a T-shaped spray ceramic nozzle (nozzle filter with 50 and 80 mesh).

After step 3 is completed, inspect the nozzle, nozzle filter, head pump filter, and top sieve filter for sieve residue with naked eyes.

The results are shown in Table 2. Example 1-Sealing under vacuum Example 2-Sealing at ambient pressure Dissolution time-the time to start the thin layer dissolution of the chamber 7 seconds 15 seconds Fully dissolved 2 minutes 5 minutes Top sieve of sprayer clean Residue Observe the main filter clean clean Observe the nozzle filter clean clean

The results show that the unit stored under vacuum (Example 1) is more stable than the unit not stored under vacuum (Example 2).

Test 3, the volume of water-soluble units (expanded) containing Gapdan after 8 weeks of storage at 40°C.

Chamber expansion is an additional test, which reflects the stability of the water-soluble unit.

Visually observe and record the chamber expansion.

The results are shown in Figures 1 and 2.

The results showed that the volume of water-soluble units that were not stored under vacuum (Example 2) (Figure 1) increased by at least 30%. in conclusion:

The present invention is a package for a water-soluble unit containing at least one agricultural raw material, which is stored under vacuum compared to a water-soluble unit containing at least one agricultural raw material stored in a sealed bag under ambient pressure (not under vacuum) The water-soluble unit containing at least one agricultural raw material in the sealed bag shows that the dissolution time of the thin layer of the chamber, the sieve residue, and the chamber expansion have little changes.

In addition, any priority documents of this application are hereby incorporated into this case as reference materials.
