<p>The present invention relates to a packaging pack which does not create a harmful material and a manufacturing method thereof. The packaging pack which does not create a harmful material comprises: a polyethylene film formed on the inner surface of the packaging pack and formed from a mixture of a low-density polymer polyethylene resin and a high-density polymer polyethylene resin; and a biaxially oriented film formed on the outer surface of the packaging pack and laminated with the polyethylene film. The present invention does not add additives such as a slipping material, an opening material (stone powder), a plasticizer of an antioxidant, a material property reinforcing agent, and a hydrophobicity agent to a base material of polyethylene (PE) at all, and maintains a slipping property which does not allow contents to stick to the inner wall inside the pack and an opening property which prevents both surfaces inside the pack from sticking to each other. Accordingly, when heating contents (e.g., breast milk or drink), harmful materials related to endocrine-disrupting chemicals are not created at all, and fine dust or the like is not created.</p> |
