Laundry pods represent another technological innovation in laundry products following laundry sheets. Their cleaning power far surpasses other laundry detergents! A single small pod can clean an entire load of laundry.

Unique packaging and convenient use are their greatest advantages. But when first trying this new laundry product, have you ever wondered:

Do I need to cut open the outer packaging? If not, will residue remain in the water? Is it safe for laundry? Could it cause health issues?

Today we'll address your concerns and delve into the details of this water-soluble outer membrane.

In fact, this water-soluble membrane is made from polyvinyl alcohol (PVA/PVOH/PVAL).

As the name suggests, water-soluble substances dissolve in water.

As a water-soluble polymer material, polyvinyl alcohol boasts excellent density, strong adhesive properties, a soft and smooth film formation, oil resistance, solvent resistance, abrasion resistance, gas barrier properties, and durability.

After special treatment, it gains waterproof properties, allowing control over water-soluble temperature and speed. Its applications span diverse industries including textiles, food, pharmaceuticals, construction, wood processing, papermaking, printing, agriculture, steel, and polymer chemistry.

Therefore, there is no need to cut open the outer membrane when using laundry bags. First, place the pod at the bottom of the washing machine drum, then pour in the items to be washed.
