Problems solved by technology

[0002] Agricultural inputs, namely pesticides and fertilizers, are widely used in agricultural production and are an important part of the national food security strategy. The current common practice in the production of pesticides and foliar fertilizers is to use bottles and aluminum foil bags for product packaging. The impact resistance and pressure resistance of the packaged products are not good enough, and they are easily broken and leaked during production and transportation, causing losses and environmental pollution

Embodiment 1

[0032] A preparation method applied to agricultural input packaging, comprising:

[0033] (1) Make a heat-sealing mold according to the size of the inner bag (height 145mm, width 85mm); cut the 0.3mm PVC film into pieces according to the height 148mm, width 88mm; A high-frequency machine is pressed into a bag; a PVC hose with a diameter of 8mm, a wall thickness of 0.6mm, and a height of 38mm is pressed to the upper end of the bag (in the middle of the two layers of the bag) to obtain an inner bag; the PVC The hose communicates with the inner bag for filling;

[0034] (2) Fill the inner bag prepared in step (1) into the foliar fertilizer, then press the PVC sheet with a thickness of 3mm and a diameter of 8mm into the PVC hose, and then press it vertically into the PVC with a diameter of 8mm and a height of 40mm The solid strips are finally pressed and sealed with a 27.12MHZ high-frequency machine. After pressing, the sealing plug of the inner bag is integrated with the PVC hos...

Embodiment 2

[0039] Step (1) and (3) are identical with embodiment 1, and difference is the sealing method of the PVC solid strip in step (2);

[0040] Since the high-frequency (high-frequency) machine is generally not available in pesticide and fertilizer factories, a chemical preparation sealing method is provided, and the inner bag sealing plug is coated with a PVC solvent (such as cyclohexanone, etc.) and pressed vertically into the PVC hose; If the sealing method of chemical preparations is used, the anti-seepage plug must be pressed flat into the injection port first. If there is no such plug and it is directly pressed into the inner bag sealing plug, it is very likely that the PVC solvent applied on the sealing plug will drip into the bag and pesticides (fertilizers) ) to react.

[0041] The size of the inner bag or the outer bag can be adjusted according to actual needs.

Abstract

The invention relates to a preparation method of an agricultural input product wrappage, which comprises the steps of: (1) manufacturing a heat sealing mould according to the dimension of an inner bag, cutting a PVC (polyvinyl chloride) film to pieces, pressing the pieces to a bag body, and pressing a PVC hose on the upper end of the bag body; (2) filling agricultural input products in the inner bag, and flatly pressing the an impermeable plug of the inner bag in the PVC hose, vertically pressing a sealing stopper of the inner bag in the PVC hose, and sealing; (3) using polyethylene granules to prepare a cylindrical material through a film blowing machine, cutting the cylindrical material, and sealing to obtain an outer bag; and sleeving the outer bag on the inner bag, and sealing to obtain the wrappage. The preparation method disclosed by the invention is simple, and the cost is low, so that the preparation method is fit for industrial production; and the prepared wrappage is good in sealing property and is unlikely to cause seepage problems, meanwhile, the impact resistance and the pressure resistance of the wrappage are greatly reinforced, so that the wrappage can be easily subjected to long-distance transport and store.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a method for preparing agricultural input packaging. Background technique [0002] Agricultural inputs, namely pesticides and fertilizers, are widely used in agricultural production and are an important part of the national food security strategy.
